Andre,

PIT is programmable interval timer and is the clocking H/W that provides 
timing to the PC Speaker, among other things.

I suspect that moving the code that locks the device for a specific 
user/use out of the pcspkr driver generalizes PIT locking for all users 
of the device not just the pcspkr driver.  I doubt it had anything to do 
with the module not being loaded after the kernel update.

What other packages were updated before you noticed the problem.  Might 
be something to do with kudzu.
