Subject: div, udiv, mul, umul, rem, urem broken again?!?

Built 2.6.14-rc3-git4 today for sparc32 and I got pages of this from
depmod -aeF /boot/System.map-2.6.13-1.1594sp1 2.6.13-1.1594sp1:
WARNING: /lib/modules/2.6.13-1.1594sp1/kernel/sound/sparc/snd-sun-dbri.ko needs unknown symbol udiv

Not just for dbri, but for pretty much everything built as a module. I
tested the latest revision of module-utils to see if it made any
difference, and it did not.
This looks like it tracks to:
http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=7caaeabb17758295edff9703c18a840073c5b8f4
Unfortunately, depmod had a workaround case for .* symbols, and it is
now seems to be broken for these sparc symbols. I worked up the attached
patch to resolve the issue, but I'm not sure if it is the most correct
way to fix it.
