Been there; done that.  On my machine I needed

  MODULES="fglrx"

in /etc/default/acpi-support if I wanted to get my screen back.
Essentially, IIUC, this means the module is unloaded just before
suspend and reloaded just before resume.

I have the strange behavior that I often can't wake up fully from resume
until I've pressed the blue "Fn" key.  A total mystery to me, but not
a showstopper.  Still, I wish I understood why this was happening.
