Or making the src.rpm available? :)

Just a note on external kernel module packaging. It is being discussed
at fedora-devel, but the main thing is that you should not use the
kernel's version/release in the package's version/release, instead the
version/release of the package should be related to the kernel module
source itself (so something like 6.1-27.2 instead of 2.6.9-27.2),
while the kernel's evr should be reflected in the package's _name_.

Even if this sounds perplexed it is the only way to allow concurrent
installs for different kernels while still allowing for smooth package
upgrades within a kernel itself.

So

GFS-kernel-2.6.9-27.2.i686.rpm   

would become

GFS-kernel-2.6.9-6.16.EL-6.1-27.2.i686.rpm   
(or in ATrpms' style GFS-kmdl-2.6.9-6.16.EL-6.1-27.2.i686.rpm)

The issues with binary kernel modules packages is that there is a two
dimensional config space in versioning (the kernel's and the module's)
and rpm can only cope with one of the two. Anything trying to mix them
(by appending them or similar) is doomed to break, unless you closely
sync kernel and GFS releases, which is not the preferred model of
updating.
