Here is a cleaned up version of the patch to repost radeon cards when
resuming from acpi s3 suspend.  I've been sitting on it for a while
hoping that I might be able to gain some insight in how to use the d2
state instead of this repost as ppc does.  On my x86 laptop with a
radeon 9000 resuming from d2 does manage to turn on the card/display,
but it becomes horridly scrambled. But right now I don't have the time
or the skill to actually get any futher than that.

And btw, posting the card still causes the system to wait for a key
press.  I don't know if that is solvable with the current post method.
Getting the existing d2 suspend/resume stuff to work might be the only
way to clear that up.
