Well, I'm confused.  When I tried 24 bit color with default
fbdev and ati a week ago, it did not work.  Now, however, it
works well although it is slower than 24 bit color with your
binary.

Result of x11perf --scroll500 with default fbdev and ati;

Sync time adjustment is 0.1741 msecs.

    200 reps @  26.9526 msec (    37.1/sec): Scroll 500x500 pixels
    200 reps @  27.0679 msec (    36.9/sec): Scroll 500x500 pixels
    200 reps @  27.0197 msec (    37.0/sec): Scroll 500x500 pixels
    200 reps @  27.1500 msec (    36.8/sec): Scroll 500x500 pixels
    200 reps @  26.9818 msec (    37.1/sec): Scroll 500x500 pixels
   1000 trep @  27.0344 msec (    37.0/sec): Scroll 500x500 pixels

With yur binary, it is around 1.5 times faster, as described
in the previous mail.

It's weird, but I can't figure out why default fbdev started
to work with 24 bit color again.  According to my poor
memory, XFree86.0.log used to show "Fatal server error:
failed to initialize core devices" in the last part,
although I'm not sure.

Anyway, thanks a lot for providing a better driver.
