Do you still have access to hardware that can reproduce this bug, and
if so, would you be interested in pursuing a fix in squeeze?

(A squeeze kernel should work without trouble on a wheezy/sid system,
so this doesn't involve installing any new packages except for the
kernel itself.  The one complication I know of is the nouveau X
driver, as documented in [1].  There is a simple workaround for it
that I can describe if that case applies to you.)

If the answer is "no", that's fine, but please do let us know so we
can plan accordingly.

Thanks for your help,
Jonathan
