i remember mention of a similar hardware, Texstar mentioned that you will need to use the ati video driver for it and that's it
i can't guarantee that, you will have to test first the hardware with a livecd to see if it boot and how it responds before any decision is taken
2011.9 livecd should be perfect for it with the latest kernel, also you could consider using pae.bfs or a64 kernel after installed
