Just a quick update with Fedora and hopefully my experience may help those that are havng trouble installing. My linux test box is a bog standard machine but has an nForce 610/GeForce Go 7050 board, it was also set up for ACHI. I disabled that set it back to plain 'ole fashioned SATA, disabled the onboard graphics and installed a 8600 GS I had lying around.
Popped in the Fedora disk (full install DVD) and bang, she fired up with no messing at all. Fedora 10 is looking rather nice at the moment and creams Ubuntu on performance. It is more difficult to get the proper nVidia drivers installed than Ubuntu and I can't get flash to work yet but we shall see.
