IIRC, there was a port of some of xscreensaver's hacks to Plan 9. The
munch hack and hyperglenda should get a good bit faster. They might
have something to measure resulting fps-es. Also, watch the CPU load
monitor while they're running.

For even more speed, define RADEON_HW_ACCEL to use the blitter's
bltblt and fillrect features (inside vgaradeon.c).

Also, unlike the VESA driver, the Radeon driver doesn't use real mode,
so it should work on SMP systems.

Does anyone know why the Radeon driver never got into Plan 9? Did no
one submit it as a patch?

Thanks,
