iPC OSx86 won't boot (halts at USBF lines)

[RELOAD911]

Hey there, I'm trying to install Mac OS X from iPC OSx86 Universal DVD (with PPF5 I suppose). I've managed to install the actual system, but it won't boot, saying the following:

USBF: 0.771 AppleUSBOHCI[hex]::CheckSleepCapability - controller will be unloaded across sleep
USBF: 0.773 AppleUSBOHCI[hex]::CheckSleepCapability - controller will be unloaded across sleep
USBF: 0.775 AppleUSBOHCI[hex]::InitializeOperationalRegisters Non-NULL hcDoneHead: [hex]

And that's it, it keeps writing "Still waiting for root device" at this point. Please help, I've tried booting with -v -f but no result so far. Thanks in advance!

You sure you chose the correct chipset during the installation ? Try to boot with -x aswell.

I've tried to boot with -x, no luck. About that chipset - I'm not quite sure which chipset kext should I choose. I could go wrong with it - there doesn't seem to be an ATI chipset kext.

ATI = AMD, and they are the SBx00 series, which you install using the VIA?something else driver package.
