SubjectRadeon xpress 200m and radeonfb kinda work
From
Hi!

I have gotten the radeon xpress 200m (the version without dedicated vmem)
to work with radeonfb.
The attached patch (against linux-2.6.20.1) works for me.
Since I don't have any docs for the card I am unsure if the patch is
100% correct.
Can someone else with a 200m try it out?
(I have tested it by enabling fbcon and radeonfb in the kernel and
added "video=radeonfb" to lilo. This gave me a nice 1280x800 console :) )
