Go into the Makefile in the top level of the source for the kernel and
go all the way to the bottom until you find the rpm target. there
should be a line that looks something like this
$(RPM) -ta $(TOPDIR)/../$(KERNELPATH).tar.gz ; \
change the -ta to -tb and it will build only the binary. Maybe not the
recommended way to handle it but it works.

you do it via a postinstall script within rpm
something like this goes in the end of the .spec file before the
changlog
this one is from the .spec for kernel-2.4.22-1.2115.nptl.src.rpm
%post
cd /boot
ln -sf vmlinuz-%{KVERREL} vmlinuz
ln -sf System.map-%{KVERREL} System.map
[ -x /usr/sbin/module_upgrade ] && /usr/sbin/module_upgrade
[ -x /sbin/mkkerneldoth ] && /sbin/mkkerneldoth
[ -x /sbin/new-kernel-pkg ] && /sbin/new-kernel-pkg --mkinitrd --depmod
--install %{KVERREL}
%{KVERREL} is defined in the spec file to produce the version and
extraversion as shown in the actual post script from the binary rpm
this is the output of:
rpm -qp --scripts kernel-2.4.22-1.2115.nptl.i686.rpm showing only %post
postinstall scriptlet (using /bin/sh):
cd /boot
ln -sf vmlinuz-2.4.22-1.2115.nptl vmlinuz
ln -sf System.map-2.4.22-1.2115.nptl System.map
[ -x /usr/sbin/module_upgrade ] && /usr/sbin/module_upgrade
[ -x /sbin/mkkerneldoth ] && /sbin/mkkerneldoth
[ -x /sbin/new-kernel-pkg ] && /sbin/new-kernel-pkg --mkinitrd --depmod
--install 2.4.22-1.2115.nptl
you will notice if you do rpm -qp --scripts on your binary rpm that was
built via make rpm that there aren't any. thats why you don't get any
of the nice automagic grub.conf editing etc...
I recommend reading the end of the Makefile for for your kernel sources
to look at how it handles make rpm. It provides some guidance on what
will happen in the process. Building a basic kernel rpm is easy doing
make rpm. Editing spec and building ones that have a lot of the
niceties the fedora/redhat ones do can be a bit harder. The spec file
from the 2.4.22-1.2115.nptl is 1691 lines itself. So hopefully the
above info gets you a little further along and my rambling message makes
some sense.
