I guess this brings up something else.

On 1/19, the Radeon driver made it into the Plan 9 distribution; anyone with
a Radeon R100 (7000, 7500, Mobility M6, M7), some R200 (8500, 9000) or
some R300s (9500, 9700) is encouraged to try them out, see if they feel faster
or work for you or whatnot.

The driver also has, disabled-by-default, hardware-accelerated fill and scroll
routines. If you wish to try them out, modify /sys/src/9/pc/vgaradeon.c to define
HW_ACCEL; I'd like to hear if they work on your card and if you can feel any
difference.

In the short term future, I hope to test the driver on a number of other cards
and add some PCI IDs/anything-else-needed, such as the R9600, 9800, and 9200/9250.
Longer-term, my goal is always support for more cards.

Take care,
