UPDATE: I am now again booting into 64bit mode, because I don't have the 32bit drivers for my USB ports.

Working:

GFX (CE/CI): still the flickering, very noticable on grey, I imagine similar to described above. Using EFI string in my boot.plist
-I have also noticed that the flickering ONLY occurs in a bar around 200 pixels thick from the left edge....

audio: Input/output all working with voodhooHDA 64bit, just native volumes control, voodooHDA prefpane can adjust volume.

Ethernet: RealtekR1000.kext working in E/E folder. 64bit enabled.

Not Working:

wg111v3 USB adapter, tried using 10.4 drivers as another person suggested, does not work in either 32 or 64 bit.

internal wifi card: Intel 5100 AGN wifi card is completely unsupported. Considering replacing this with a dell miniPCI card.

-----------------------------------------

Thanks for your help and suggestions so far.

will it be possible to change the PCI wifi adapter? I can buy a fully supported dell card on ebay fairly cheap, and this would function with airport.

I read somewhere thatI might have to flash a custom BIOS onto my board, because HP has a whitelist for Wifi cards.... anyone have info?

so close!
