update: I think I may have found the problem. Whenever booting into
Gnome, I got an error message that said "wrong permissions
for /dev/pmu". I hunted around and found that the way to fix it is
"chown root:user /dev/pmu" then to add yourself to the video group.
Following a reboot, suspend and wake seem to be working again!
Interesting sidenote: I tried installing udev and it seems that udev
will "correct" the ownership of /dev/pmu so that it's "root:root" again,
which causes the black screen on wake problem again. apt-get remove
udev, then chown'ing again as above solves that.
Thanks for your help, folks!
