Yes, it does. Thanks, now my HP-dv5 is happy.
I did some tests suspending with the caps lock actually on, and it seems that
in that case the user might still be confused (caps lock is on but led is off).
At least on this machine this patch doesn't affect this theoretical problem
either way (2.6.31 behaves similarly), so it is ok.
