Snow doesnt need an AppleCPUPowerManagement disabler anymore?

I redid a test install of SnowLeo and I didnt put any disabler kext and it booted and everything seems to be working without any extra disabler (only FakeSMC v2, OpenHaltRestart and PlatformUUID and VoodooPS2, boot is netkas pcefi 10.3).
The mobo is an AsRock P45TS, its DSDT its pretty standard, meaning it would need a patch to run vanilla AppleCPU kext I think:

CPU:

Code:

DefinitionBlock ("dsdt.aml", "DSDT", 1, "AS148", "AS148142", 0x00000142)
{
    Scope (_PR)
    {
        Processor (P001, 0x01, 0x00000810, 0x06) {}
        Alias (P001, CPU1)
        Processor (P002, 0x02, 0x00000000, 0x00) {}
        Alias (P002, CPU2)
        Processor (P003, 0x03, 0x00000000, 0x00) {}
        Alias (P003, CPU3)
        Processor (P004, 0x04, 0x00000000, 0x00) {}
        Alias (P004, CPU4)
    }

HPET:

Code:

                Device (HPET)
                {
                    Name (_HID, EisaId ("PNP0103"))
                    Name (CRS, ResourceTemplate ()
                    {
                        Memory32Fixed (ReadOnly,
                            0xFED00000,         // Address Base
                            0x00000400,         // Address Length
                            _Y0F)
                    })
                    OperationRegion (^LPCR, SystemMemory, 0xFED1F404, 0x04)
                    Field (LPCR, AnyAcc, NoLock, Preserve)
                    {
                        HPTS,   2, 
                            ,   5, 
                        HPTE,   1, 
                                Offset (0x04)
                    }

                    Method (_STA, 0, NotSerialized)
                    {
                        If (LEqual (OSFL (), Zero))
                        {
                            If (HPTE)
                            {
                                Return (0x0F)
                            }
                        }
                        Else
                        {
                            If (HPTE)
                            {
                                Return (0x0B)
                            }
                        }

                        Return (Zero)
                    }

                    Method (_CRS, 0, NotSerialized)
                    {
                        CreateDWordField (CRS, \_SB.PCI0.SBRG.HPET._Y0F._BAS, HPT)
                        Multiply (HPTS, 0x1000, Local0)
                        Add (Local0, 0xFED00000, HPT)
                        Return (CRS)
                    }
                }

RTC:

Code:

                Device (RTC0)
                {
                    Name (_HID, EisaId ("PNP0B00"))
                    Name (_CRS, ResourceTemplate ()
                    {
                        IO (Decode16,
                            0x0070,             // Range Minimum
                            0x0070,             // Range Maximum
                            0x00,               // Alignment
                            0x02,               // Length
                            )
                        IRQNoFlags ()
                            {8}
                    })
                }

Also I got this line in the log when booting a freshly installed SL:

Code:

Sep 28 04:59:54 localhost kernel[0]: AppleIntelCPUPowerManagement: Enabling legacy HPET check
Sep 28 04:59:54 localhost kernel[0]: AppleIntelCPUPowerManagementClient: ready
Sep 28 04:59:54 localhost kernel[0]: AppleIntelCPUPowerManagement: initialization complete

Not only its loading without errors, it also support something called legacy HPET????

On the other hand I get these 2 messages I didnt see with Leopard before (most likely not related but...):

Code:

Sep 28 04:59:54 localhost kernel[0]: RTC: Only single RAM bank (128 bytes)
Sep 28 04:59:58 localhost kernel[0]: ** AppleSMBusPCI::start failed to get acpi path for provider

The last one you can guess its the SMBus device not loading correctly but the one about the RTC I dont understand what it is (I got 2 1 gb DDR2 sticks, dual bank from what I know, not sure...)

Could it be something changed in AppleIntelCPUPowerManagement or am I missing something? I'm pretty sure I'm not using any disabler from other folders nor using a patched DSDT without knowing it...
