Public bug reported:

After suspend / resume, screen is blank.  The video card in this machine
is "M92 LP [Mobility Radeon HD 4300 Series]" and I think the fglrx
driver doesn't recognize this (see attached Xorg.0.log).

I found the solution was to add a file: /etc/pm/config.d/unload_modules
containing:

  SUSPEND_MODULES="fglrx"

I hope the fglrx-installer package can add this automatically in future.
