i can get this too, but only if ALSA's isapnp module is already loaded
when i do the modprobe. If i rmmod that isapnp module before
i /etc/init.d/alsa start, it all loads fine. Also, if i do the modprobe a
second time (after the segfault) it all works fine.

A patch is attached that'll remove the isapnp module on /etc/init.d/alsa
stop. As root, cd to /etc/init.d and "cat patch | patch -p1".

Yeah, i noticed that too. Looks like someone already filed the bug report
though.
