Sound broken in 8.04

[Sean Carolan]

Yes, I'm living on the bleeding alpha edge.  It's not so bad out here
except the tragic loss of my sound system.  Right after upgrading to
this kernel:

root at kalki:~# cat /proc/version
Linux version 2.6.24-12-generic (buildd at palmer) (gcc version 4.2.3
(Ubuntu 4.2.3-2ubuntu2)) #1 SMP Sat Mar 8 02:29:24 UTC 2008

Sound abruptly stopped working.  I have a whole lot of "Unknown
symbol" errors in dmesg.  This is my sound card info:

00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS]
AC'97 Sound Controller (rev a0)
