For Linux 2.6 you cannot do that.  For a 2.6 kernel you ABSOLUTELY MUST
build the kernel module against the ACTUAL header files for /that particular
kernel/.  In other words, there is exactly a one-to-one mapping from
/lib/modules/xxx/build to kernel module.  You CANNOT build multiple
modules from one kernel source tree.

Now, having said that, I wrote a script that does a full build of modules
for all kernels.  If you run /usr/src/redhat/SOURCES/openafs-buildall.sh
it will build the base module and then all the kernel modules for your
particular system.  For 2.6 it looks in /usr/src/kernels/ for the set of
kernel headers, and it will build a kernel module RPM for each kernel
it finds.

Just to be clear, for 2.6 kernels you CANNOT build multiple modules from
a single source tree.

In your case, `uname -a` is reporting a UP kernel, so it's building a
UP module.  This is not a bug.

As for having all kernel modules in one RPM, I've said before and I'll say
again that I'm willing to accept a patch that reinstates that functionality
based on some --with XXX value, but I have no intention of actually
implementing or supporting such a feature myself.  I personally believe that
the one-RPM-per-kernel is the right approach for the general population.
