[PLUG] Monitor Troubles Waking from Sleep

I've been having a problem when my Gentoo desktop awakens from sleep or
hibernation.

I've got a 3-monitor setup, with the middle monitor rotated to portrait
mode.  For the last month or so, whenever the system awakens from sleep,
the middle monitor returns to landscape mode instead of staying in
portrait mode.  [Luckily, it helpfully opens up the xfce display setting
program automatically because it somehow knows it's hosed my displays.]

I can execute a simple xrandr script to reset the displays, or futz with
the display setting application, but this is a pain.  A while ago,
everything just worked, but I'm on the bleeding edge with Gentoo (~AMD64
mode), so I have to accept a few problems.

Anybody have an idea where I can look to troubleshoot this?

Alternately, is it possible to run a script when a system comes back
from sleep/hibernation?

TIA for advice!

Casey
