No, I haven't had a chance to test the suspend/resume behavior,
because that requires suspending at work, going home, and connecting
to a dock which has a different monitor attached to it, and resuming
(or vice versa of suspending at home and then resuming at work).

So it's a bit trickier for me to test.  It's also not a regression,
and the workaround of rebooting is annoying, but I've lived with it
for several releases now, but I'll try the two patches/changes that
folks had suggested hopefully later this week.
