Fwd: OK, I had to do it again (disk transplant from a i586 to a i686)...

I posted this to the linux.redhat.com newsgroup and didn't get a reply. 
I now need to apply some updates, but can't do things automagically with
yum because of this problem (I'll have to update some packages manually
with 'rpm --ignore-arch ...', which is a real PITA).  I did a google
search and cannot find any documentation on how to fix this.  Do I
really need to do a fresh re-install?  Arg!!!
