Just got word from Zardon @ Driver Heaven that there's a new set of Plutonium XP 8.1 drivers out based on the 6166. Plutonium drivers are customized ATI drivers. This Windows XP driver supports the following radeon family devices:

Radeon 7000 / VE
Radeon 7200 / SDR / DDR
Radeon 7500
Radeon 8500 / LE / LELE
Radeon 9000 / Pro
Radeon 9700 Pro
All in Wonder Radeon SDR / DDR
All in Wonder Radeon 7500
All in Wonder Radeon 8500dv
All in Wonder Radeon 8500 (128mb)
Mobility Radeon (M6)
Mobility Radeon 7500 / FireGL 7800 (M7/M7-GL)
Mobility Radeon 9000 / FireGL 9000 (M9/M9-GL)
All other powered by ATI radeon devices


What's New

Windows GUI Acceleration problems should be fixed.
Hopefully improved more upon 9000/9700/M9 Support.
CPanel integrated directly into driver INF (Should help some people with CPanel problems).
Did more testing on R100 chips.
6166 Driver fixed the Mozilla freezing bug.
NOTE: ATI Icons removed from advanced tabs on purpose, not a bug.
Modified WDM Included (Based on 6.13.6142).
* file size signifigantly reduced to under 13.5
