I narrowed this down to a broken RPM provided by HP, specifically hp-
OpenIPMI-7.5.1-8.rhel4.i386.rpm.  This RPM includes a module-compilation
script which actually moves /boot/kernel.h to /boot/kernel.h.ORIG and
copies a uniprocessor file into /boot.  It does this to compile a
uniprocessor kernel module.  On top of this being wrong, the file it
puts in place has the identifier "i686-smp" although SMP is 0 and UP is
1.  This is why /sbin/mkkerneldoth never updates the file.

Thanks to HP for breaking hundreds of servers which I now need to clean
up manually (i.e. rm -f /boot/kernel.h; /sbin/mkkerneldoth).  Needless
to say, we've removed hp-OpenIPMI from the yum repos we use for third-
party and internal software on top of RHEL.
