Tried to add the default modes from the old driver as modelines, and
with the 6.7 from experimental it works. The driver rejects the larger
modes because they are too large for virtual size.

However, on the very system where it fixes the mode selection it
caused a lockup.

01:00.1 0380: 1002:5940 (rev 01)

Radeon 9250 (reported as Radeon 9200 PRO) rv280

Should I file a different bug about the lockups or is there one among
the zillions of Radeon bugs already?

Thanks
