Hi!

The situation:

I have a radeon 9200 (RV280 RADEON_Ya).
I easily added support for it to kernels test8 and test8-mm1.
test8 kernel have old radeonfb driver.
test8-mm1 kernel has benh's new radeonfb driver (or some strange derivative).

The problem:

test8 works nicely in all resolutions including 640x480-60 and 1024x768-75.
test8-mm1 only works at 640x480-60, anything else is black or distorted.

The evidence:

As the attached files can attest, both kernels have exactly the same timings
for a given resolution but different debug printk's.  test8-mm1 has text accel
enabled and test8 disabled.  Forcing test8-mm1 to accel disable does not make
any difference.  AFAICS the only difference are the debug printk's which i
can't remotely interpret.

The beg for help:

Can somebody look at the attached files and deduce what is going wrong?
Or point me to a better source of debugging info.
