I suspect it's a problem similar to one I've been having, and am
investigating.  I upgraded to X.org 7.3, and have since then had problems
with ACPI events screwing up my X session (to the point that it make the
OS as a whole pretty much stop working except via SSH for remote access).

I have problems with not only sleeping, but also starting X if my laptop
is running on its battery (thus with scaled-down power usage) instead of
being plugged in.  Even when starting X (successfully) while plugged in,
however, it puts some interesting garbage on my screen for a few seconds
before it starts working properly.
