You should not have done this. I guessing that the CentOS 5.5
installer is not bulleted proofed for this case (eg it assumed that you
know what you were doing). In any case, this is not a supported way to
go (documented or not). The 'updater' on the CentOS 5.5 x86_64 DVD is
meant to go from CentOS < 5.5 x86_64 to CentOS 5.5 x86_64, NOT CentOS <
5.5 32-bit to CentOS 5.5 x86_64.
You should have made a backup and then did a fresh install.
The only good way to properly fix things is to backup your stuff (eg
/home/ and stuff like /var/www/ (if you are running a web server)).
Maybe backup selected files under /etc/ (eg passwd, shadow, group, etc.)
and then do a fresh install (*reformat* /, /boot, /usr, etc.).
