BTW, I noticed an interesting x11perf score. x11perf -scroll500 marked ~300/sec
for ATI Rage128RE connected to 66MHz bus on B&W G3 rev.1, but ~600/sec for an
old Matrox Millennium II to 33MHz bus, measured at 32bpp/24bit depth.

are you using the patch I posted last week?  If not, then I suggest you

Yes, I am. But Rage128RE score was only ~300/sec at 1280x1024x32bpp/75Hz.
(The score is very sensitive to actual(not virtual) screen size and refresh rate).

do.  I fixed the improper load/stores in r128 and it shows a 200% increase
in almost all x11perf tests.  example:

(jack howarth tested these on his g4/450 (rage 128pro?)):

before:
Scroll 500x500 pixels:	583.0/sec

after:
Scroll 500x500 pixels:	1060.0/sec

The old Millennium II had dual-ported WRAM, so the accel engine wasn't
sensitive to refresh rate. But single-ported commodity SDRAM/SGRAM is cheaper,
so WRAM was killed.
