So, now that this has run its course (yet again), can I ask that my
patches be applied?  Those that create a kernel.spec %posttrans, which
invokes new-kernel-pkg --rpmposttrans, which invokes the scripts in
/etc/kernel/postinst.d/ ?

If running all of /etc/kernel/postinst.d/ is so scary, I'm ok with
new-kernel-pkg explicitly doing

[ -x /etc/kernel/postinst.d/dkms ] && /etc/kernel/postinst.d/dkms $kernelver /boot/vmlinuz-$kernelver  

but I think we've beaten the fact that RPM can't do what I need
(today, that could be changed, but I don't really want to wait forever
for that to happen...).
