I've been meaning to do this one for a while and I now have it working so
that with my current -ac kernel working tree I can type

	make rpm

and out puts kernel-2.4.7ac3-1.i386.rpm

All this took was the pieces below.

Anyone care to knock up a "make dpkg" to go with it ?

#
# RPM target
#
#	If you do a make spec before packing the tarball you can rpm -ta it
#
spec:
 	. scripts/mkspec >kernel.spec

#
# 	Build a tar ball , generate an rpm from it and pack the result
# 	There arw two bits of magic here
#  	1) The use of /. to avoid tar packing just the symlink
# 	2) Removing the .dep files as they have source paths in them that
# 		will become invalid
#
rpm:    clean newversion spec
        find . \( -size 0 -o -name .depend \) -type f -print | xargs rm -f
        cd $(TOPDIR)/.. ; \
        ln -s $(TOPDIR) $(KERNELPATH) ; \
        tar cvfz $(KERNELPATH).tar.gz $(KERNELPATH)/. ; \
        rpm -ta $(TOPDIR)/../$(KERNELPATH).tar.gz

#
#	The only gothic bit here is redefining install_post to avoid 
#	stripping the symbols from files in the kernel which we want
