Here, at least, ALSA 0.9.0-rc3 causes a NULL pointer dereference, then
leaves the kernel in an unusable state (only sysrq-B does anything worth
mentioning)  I'll be trying CVS later today, and if that doesn't work,
I'll try out beta12, and report it to the alsa list.

By the way, does anyone know if ALSA plans to support the cs4610/11 that's
in thinkpad 600E's natively?  Also, am I correct in thinking the reason they
aren't right now is because the thing's attached to a cs4239 instead of a
ac97 like most of the cs4610/11's?
