Hmm, with the -F it works fine. I suspect that the past depmod was able
to pick up /boot/System.map-2.4.22-xfs and use it implicitly for me but
the current depmod here doesn't. Thanks for the info... I've rerolled
the kernel with modules again and the=20
$ depmod -F /boot/System.map-2.4.22-xfs -e -a 2.4.22-xfs
is happy now.

Not looking into the patch city that was in the CCRMA kerenl in any
great depth what level of interest is there in having yet another CCRMA
kernel with original CCRMA + dm + evms + xfs in it?

The main icky parts are getting the evms-2.2.0 and device-mapper
userland stuff installed both of which want a little hack in rc.sysinit.
