Excellent work, PCJ
This approach is very clever.

I can verify that PCJ's way is working perfect for me.
His boot + Vanilla 10.4 or 10.5 ( depends on your Mac OS X version is 10.6.4 or 10.6.5 ).
Sleep works too ( need NullPowerManagement.kext + SleepEnabler.kext )

Not sure if this also works for AMD, I think it should be working for Netbooks (not tested)

Without using Vanilla kernel, several apps have trouble such as CleanMyMac it cannot detect platform of the Mac either Intel or IBM.
