still a problem for me on dv8000.
I've been using hibernate to get around it, and it still bites me when I resume 
hibernated image: if I don't take care to keep AC power disconnected over the 
whole hibernate->resume process, it sees the power event & resumes into a fatal 
suspend.
But if networking is up, I've been able to rescue from this state by ssh'ing in 
& forcing another hibernate, this time keeping AC on until resumed (or AC off, 
just don't change it midway).

So my guess is that the keyboard driver is getting unloaded by suspend, but not 
re-modprobed by wakeup.
Resume-from-hibernate does re-modprobe the keyboard, so can unstick it.
I recall trying to modprobe a guessed missing keyboard module by hand over ssh, 
which didn't work, so I've either got the wrong hypothesis here, or merely the 
wrong kb driver name
