dmasound failure under 2.2.12 kernel

[Michael G Schwern <schwern@pobox.com>]

I recently upgraded from my own 2.2.11 kernel to the new
kernel-image-2.2.12-pmac and I've found that sound has ceased to work.
This is a WallStreet PowerBook G3.  I've traced the problem to the dmasound.o
module:

# modprobe /lib/modules/2.2.12/misc/dmasound.o
/lib/modules/2.2.12/misc/dmasound.o: unresolved symbol machine_is_compatible

I got the same problem when I compiled the kernel myself (gcc 2.95.1)
from the kernel-source-2.2.12 and kernel-patches-2.2.12.  I have yet to try
compiling straight from the pure Linux source.
