Sleep on AMD - report your experience

I know, it's a well discussed topic, but it always ends with "Hey, we're AMD, not Intel". I think that's no reason to capitulate, so let's start collecting information about sleep on AMD. I think it's not only up to the processor, but to the mobo - so let's collect information about your success or non-succes with sleep on your AMD-System. Please post your specs, too, so we can compare and draw a conclusion. I'll start.

My success with sleep on my AMD with the SleepKernel looks like this:
- changing ACPI-Mode in BIOS to "S1" and changing ACPI-Mode in system, too, let my sleep work - but only a "half-sleep". Hard drives are shut down, but the fans still are turned on, so no really success.
- changing ACPI-Mode in BIOS to "S3" and changing ACPI-Mode in system, too, brings my system to the deep-sleep. No noise, but wake up doesn't work. Just a black screen and a running system.
- changing ACPI-Mode in BIOS to "S1 and S3" and changing ACPI-Mode between "S0, S1, S3, S5 and S7" doesn't work, too. System gets into "half-sleep" and can't be woken up.

My system specs:
AMD Athlon 64 3200+ Venice (SSE3)
NVidia GeForce 6600GT PCI-E (working with NVInject, dual screen working with DVI-VGA converter)
EPOX 9HEAI Rev 3 Mainboard with VIA K8T890 and VT8237R chipset
 I think the rest doesn't care to this topic

My experiments worked like this:
- changing the kernel from default Zeph-Kernel to SleepKernel (by using Kalyway kernel installer - see attachment)
- changing BIOS ACPI-Mode
- changing system's ACPI-Mode by typing following commands in Terminal:

Check current ACPI-Mode
pmset -g | grep hibernatemode

Change ACPI-Mode
sudo pmset -a hibernatemode X

X is the number of the ACPI-Mode. Here a list of the available modes:

# 0 - Old style sleep mode, with RAM powered on while sleeping, safe sleep disabled, and super-fast wake.
# 1 - Hibernation mode, with RAM contents written to disk, system totally shut down while “sleeping,” and slower wake up, due to reading the contents of RAM off the hard drive.
# 3 - The default mode on machines introduced since about fall 2005. RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically.
# 5 - This is the same as mode 1, but it’s for those using secure virtual memory (in System Preferences -> Security).
# 7 - This is the same as mode 3, but it’s for those using secure virtual memory.

That's all for my sleep-success with OSx86/AMD. Please attend at this topic, I think it could be useful for the evolution of OSx86 on AMD-Processors.

Attached is the Kalyway Kernel Installer with all available kernels. If you want to try sleep at your system, the first step is to install the SleepKernel.
