Anyway, the garbled screen issue is usually associated with the caching
method used on the PCI GART. On IGP chips we force the GART to be
uncacheable. On PCI chips they are supposed to be able to snoop the bus
and DTRT. All of the fixes for memory caching should be in 7.
Please try the attached patch and see if that makes a difference.

Unfortunately, this didn't help. I should also clarify what I'm seeing,
as it's not complete garbage as I thought. I have a dual monitor setup,
side-by-side using xrandr. When I start X (xfce4) with drm available,
the left monitor (primary) is a sold light shade of blue, except for a
black corner which is maybe 10pix square. The right monitor displays my
typical background image with another black box over part of it. If it
shift back to the console and then back into X, I can see the outlines
of my startup windows, but they contain garbage and the outlines are
fuzzed with green and magenta garbage.
