Hmm, the 433 I had the chance to play around with came with a TurboVRX 3D graphics device, an external box with lots of RAM, an i860 and some 
other stuff inside that connected to the 433 with a DIO-II board and a rather thick ribbon cable. 
Because these beasts were rather expensive there weren't much, so it's unsupported. 
btw. even some supported framebuffers are external ( think gatorbox... )

have fun
