    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 :) )
