Maybe the software does not prepare the hardware correctly before
suspend, then the hardware state is screwed after resume and the
software is not able to restore it to a correct state even when
reloading kernel modules and X.
Unfortunately, the support for suspend still has lots of bugs and I
don't see a lot of fixes coming from upstream...
Are you doing suspend-to-disk or to-ram? Does it help if you switch to
VT console before suspend? Does suspend work better with XAA?
