I've had the same issues on four Dell Optiplex SX270 computers. These all use the Intel 865 chipset and ended up using software-only rasterizer for 3D acceleration. I used G. Christ's intel driver provided above and the cards started working. I still get occasional freezing when trying to run XBMC under linux though (haven't really tested a lot of other linux programs since these computers were built as HTPCs)
