You must be looking at it wrong. I have several large RHEL5 installs with
_NO_ 32-bit packages or 32-bit dependencies. x86-64 only. No way will a
64-bit package have a 32-bit dependency.

rpm -e mysql; yum install mysql.x86_64 ought to do it. If you don't trust
it, just mv the /var/lib/mysql directory to /var/lib/mysql.bak first then
move it back after the upgrade. You may also want to back up your
/etc/my.cnf file before the upgrade.
