Unfortunately the stock video options (ATI FireGL X1 and X3) give an incredibly slow unaccelerated 2D due to failure to kickstart the command processor (radeon open source driver).

PCI isn't really the root bus so it's a bit odd. If you can live with 1024x768 then the ancient PCI Voodoo2 graphics cards in 2D mode don't even report as video cards, have minimal setup requirements and work on just about anything with a PCI bus. They are also usually available in the "junk box under the table" at computer shows. 3D is a bit trickier but the 2D acceleration is quite nice and can even do alpha blending (as it was in part designed to work with the 3D). Actually doing 3D is a different kettle of fish.
