Hello.

Attached patch does the following:
- changes the pcspeaker driver to
use the i8253_lock instead of i8253_beep_lock
- adds the SND_SUSPEND event that allows
to disable and re-enable the driver. It
is necessary, for example, for the PCM
PC-Speaker driver (which is currently in
an ALSA CVS), as it doesn't want to
interfere with the pcspkr, so it needs
some way to disable the thing.

Can this please be applied?
