That may be a problem, too, but I don't think that will fix my problem. 
Something went wrong with the kernel + modules ebuild.  The normal output
of the kernel sequence, ie make mrproper, make xxxconfig, make deps make,
make modules and make modules_install is a bzImage (ebuild got that right)
and a modules directory /lib/module/kernelname (ebuild did not produce
this), so the merge really failed even though it said it was complete.  It
won't do me any good to rebuild the modules.conf etc - the modules
themselves are missing in action.
