Module.symvers should be part of kernel-devel.
I often build the openafs module (via the Makefile, not rpmbuild) on
fedora with fedora-built kernels, and I can't recall ever having to do
anything else other than installing kernel-devel for the corresponding
kernel. I've certainly never had to use "make prepare" or "make
I just did a quick test with a 188.8.131.52-68 kernel with the kernel and
kernel-devel RPMs, and a bogus configure test that uses a GPL-only
symbol. I got the expected "modpost: GPL-incompatible module
conftest.ko uses GPL-only symbol" error.
