Radeon xpress 200m and radeonfb kinda work

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 :) )

Please CC, I'm not on the list.
