nice! it works fine with voodoo-3 3000 too!

test machine: single celeron 300 at 450, in old abit bx6 board (intel 440bx)
voodoo3 3000 agp, at 640x480x32bpp, tdfxfb from 2.4.18:
sound: sb 16 isa pnp (using OSS driver of kernel)

mplayer -vo tdfxfb Coyote.Ugly.Sample-highbitrate-atmos.avi -benchmark
-quiet -aop list=resample:fout=44100 -vc XXX [-dr|-noslices]

comments:
- displaying yuy2 seems to be much faster, than yv12 (~5.2 sec vs. ~23 sec)
it's strange, especially as yv12 needs less memory transfer!
yuy2 may be faster due to one big linear copy, while yv12 copies many small
lines... maybe separating the 3 plane memcpy loops may help?

- latest divx4linux (divx4linux-20011025.tgz) has horizontal stride bug
decoding divx3 content, at least triggered by this file

best decoding performance: ffdivx
best total performance: divx4+dr

hey, voodoo3 + tdfxfb really rocks, ~ 7% cpu usage for full 640x480 yuy2
blit is really nice for such slow system!
