I got a HP EliteBook 2530p on u9.10 with the same problem. Though it's
has a fancy behaviour: First of all, after resuming the touchpad is
going rogue and doesn't work anymore. If I use only the pointer stick,
everything is fine, keyboard works as well. Yet, the first slide over
the touchpad ends up in a unpredictable keyboard/mouse input and
keyboard+stick+touchpad is ending up dead or bogus. Now, if I standby
and resume again, either everything work fine right away, or I can use
tab or stick to "Switch User" in the "Unlock Screen". Then X refreches
someway and everything is fine again and I select my user and unlock the
screen. The cherry on the cage, this is without exception an alternating
behaviour. I'm already used to wake up the thingy by a resume+immediate
standby+resume again.
Xorg.0.log says:
---------------------------

and in /var/log/messages I realized the following lines are missing, for
wake-ups with the problem:
