I can't say for sure why does the
crash happen, but what is known is
that you need a very recent alsa-lib
to get pc-speaker working properly.
And  even 1.0.16 is not modern enough
for that. :(
But that's not a big deal.
The attached config is only what's
needed. Put it into /usr/share/alsa/cards
and /etc/alsa/cards and maybe that
will help. There should be already
the file with that name - overwrite it.

The easiest solution is
---
options snd-pcsp index=2
---
into /etc/modprobe.conf. It will
then not go ahead of 2 other drivers
of yours.
