That's not my experimented with a banshee. Using xv is the worst, then
come tdfxfb and finnaly tdfx_vid. However using tdfx_vid i have mostly
the same performence on the framebuffer and under X (on a k6-333).
Try a vidix/*_vid vs. xv on a box with a <= 500 MHz CPU and you'll
see that xv is just slooooow.
