You misunderstood me. I'm using a 6950 (not CAICOS) and it was working great
with commit
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=81ee8fb6b52ec69eeed37fe7943446af1dccecc5
for my Cayman (but not for CAICOS according to reporter of bug 42373) included
in kernel 3.6. What I'm saying is that the symptoms I'm now seeing with 3.7-rc1
are similar to what I was seeing at the time, but it was fixed in 3.6.

Now, about the patch you propose, it is already included in kernel 3.7-rc1
according to commit history. Since I'm experiencing bug 55692 with 3.7-rc1, the
proposed patch can't be the cure. I'm bisecting right now between kernel 3.6
and 3.7-rc1. If it appears to be a different bug than 55692, I'll open a new
one.
