Geoff Teale, given the DRI report is similar problem, different hardware
model, and it has many "Me too!" comments, those types of reports tend
to be lost in the shuffle.

However, a couple of follow up questions:
1) Just to clarify, did the patch mentioned in https://bugzilla.kernel.org/show_bug.cgi?id=46241#c8 address your problem?
2) Did this problem not occur in a release prior to Precise?
3) Does fglrx provide a WORKAROUND?

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

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

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.

  My setup is a Lenovo Thinkpad E525, AMD A8-3500m.
