Thanks!  It seems to have suffered from paragraph reformatting a bit,
but the killer line is:

rm -f /usr/src/redhat/BUILD/comedi-cvs20060704/./confstatzm7977/*

In the kernel Makefile for 2.6.17, that comes from the line:

        $(Q)rm -f $(MODVERDIR)/*

2.6.16 has a similar line:

        $(Q)rm -f $(MODVERDIR)

so I'm not sure why _that_ worked!  (I may investigate further if I have
the time.)

Anoyhow, I fixed it in CVS (see attached patch) by not setting MODVERDIR
on the command line and letting the kernel Makefile figure it out by
itself.  You need to re-run ./autogen.sh with your current ./configure
command-line options after applying this patch.
