Um, what's kernel-rt got to do with anything I said? And actually, the
first server I'm trying to build this on is a Sunfire, but it's running
Opterons, and the o/s is 64-bit. I also do *not* have any xen installed.

Fine, I tried running
 rpmbuild -ba --target=x86_64 --without xen video4linux-kmod.spec
Building target platforms: x86_64
Building for target x86_64
error: Failed build dependencies:
        kernel-xen-devel-x86_64 = 2.6.18-194.3.1.el5 is needed by
video4linux-kmod-0.0-5.20090615.el5.elrepo.x86_64

My last trick was to edit the stupid spec file, and comment out
#%ifarch i686 x86_64
#%define xenvar xen
#%endif
and it *still* wants to build for xen.

No, the rpmbuild is not correct. So, back to the original, of trying to
figure out just what kernel modules I need to install, rather than the
laundry list it correctly builds when I drop the rpm, and build from the
blown-out tarfile.
