Yesterday I've succesfully installed this distro...

How I fixed things...
Because the original distro does not support 4GB RAM, so I don't think it supports 8GB RAM also... I've edited the distro with Transmac, and added the latest NForceAta drivers... (I think you'll find these at insanelymac), then burned my edited distro - et voila!...

Sound didn't work either, for which I installed the AC97 driver from another distro - I think it was iAtkos v7

Internet didn't work in the beginning but also updated that with another driver...

And then last but not least I got my 8800GTX running with NVinstaller v.52...

For your config I would first try with adding those latest NforceAta drivers to your distro... Let me know if this works...

EDIT::: I forgot to mention that I managed to get this installed with an IDE DVD-drive and an IDE HD... Maybe find yourself a temporary IDE-dvd drive...
