I see now... I DID test the '--quirk-s3-bios' flag, but I need '--quirk-
test', which is not documented in the manpage...

from pm-utils-1.4.1/README.debugging:
"* To override the usual quirk filtering (for kernel modesetting, binary drivers, and exotic hardware), pass --quirk-test along with any other quirks you want to try.  This may make your system crash in new and exciting ways by conflicting with the kernel when suspending or resuming, but is very useful for debugging.  You have been warned."
Oh, well, I'm happy that someone found a solution and shared it with us all :D

Title:
  1002:9641 [Lenovo ThinkPad E525] Screen black on resume

Status in Direct Rendering Infrastructure:
  Invalid
Status in The Linux Kernel:
  Fix Released
Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  I did the kernel smoke test for the quantal kernel on precise.

  I can suspend and resume however when I resume I the screen stays
  black. It looks like the backlight isn't coming on, but it's noteable
  that I don't see anything on my external screen either. I can see
  consoles on my external monitor (over HDMI) and if I disconnect the
  HDMI cable and reconnect it then I am also able to see my Unity
  session on that screen. This issue is present with both the quantal
  kernel and the stock 12.04 one.

  WORKAROUND: Use fglrx.
