Hi Linus,

all radeon fixes, one nasty startup crash and/or memory corruption on one
family of radeon hd6450s resulted in a patch to stop setting a bunch of
regs in the drivers and let the BIOS set them correctly, displayport
regression fix, and some off-by-one in the cursor code around the corners
of the screens.

its a bit bigger than I'd like but the register setting removal had to
remove the unused functions.

Dave.

Has this been tested with suspend/resume on a lot of machines?

In general, the registers that get set on boot correctly absolutely do
*not* get set on resume.

So the registers that you now no longer set at boot-time should almost
certainly still be saved and restored across suspend/resume. I don't
know the code well enough to read the diffs, but a quick grep seems to
show that when you removed the boot-time setup, you also removed the
resume-time setup (well, at least MC_SHARED_CHREMAP doesn't seem to be
used anywhere any more: it may be that it's saved-restores in some
kind of "loop over all registers" that wouldn't have triggered the
grep).

I pulled, but please verify that whole thing.
