While having a 2nd kernel is a wise choice, there's little reason to avoid
Uvh in this particular case since the only difference in the files is the
architecture that it was compiled for. Since i386 is backwards compatible,
with i686, little is lost.

Now if "-Uvh"ing (if you're sure it works after testing i.e. on a server
farm of identical hardware), you may get a brief but relatively harmless
"tizzy" from the kernel if it tries to load an obscure module before you
reboot. Otherwise, this is something I've gotten away with 99% of the time.
Only time it used to bite me was on the old 7.0 and 7.1 machines using lilo
when mkinitrd wasn't properly called afterwords. 7.2, 7.3, 8.0, and 9 have
worked flawlessly. While more risky, it's a calculated risk based on the
fact that it worked on the other machines, it'll work here too.

My 2 cents. Feel free to do it how you choose :-)
