This is very interesting, since I saw that elrepo did succeed in building 
kmod packages for 32bit PAE of the exact same version. So I was wondering 
if you may be missing the kernel-PAE-devel package or something causing 
the build to fail.

Normally you can find the reason for failed dkms builds somewhere inside 
/var/lib/dkms, maybe easiest to do a:

 	find /var/lib/dkms -name make.log
