> What's likely is that you're hitting several problems at once:

I minimized the number of errors by unloading ALL modules before
trying to suspend. Finally, it came down to what seemed like just
one error message while resuming:

kernel: MCE: The hardware reports a non fatal, correctable incident
occurred on CPU 0

So I booted up with the "nomce" option and the acpi option you had
below and now the MCE error does not show up while resuming.. but I
still don't have display after resume.

Hopefull I'll get to the point where the only things that don't work
on resume are the keyboard/mouse.

Yes, I unloaded all USB drivers before suspending.

This definitely seems to be the issue.. wonder if this will help but
here's the output on resume (and the last line from suspend) from
syslog:

I don't see anything suspicious here.. please let me know if you see
something...
