You know, I'm not even sure of the details now, but I used myHack to create the USB drive (I'd done it by hand earlier, but ended up throwing that out and starting from scratch, myHack was quicker to do )
I used the DSDT that simeonoff posted in the 'OSX Lion on D630' thread, along with the Extras someone had suggested - sim's set wouldn't boot for me.. I was getting ACPI KP's quite regularly with a lot of sets, not sure why.
Kexts's in the installer usb drive are: FakeSMC, IntelCPUMonitor, lspcidrv, NullCPUPowerManagement, VoodooBattery, VoodooPS2Controller and VoodooTSCSync
On my installed system, I have BCM5722D, FakeSMC, IntelCPUMonitor, lspcidrv, VoodooBattery, VoodooPS2Controller, and VoodooTSCSync
