There is a known issue with yum.  See, for example,

http://lists.centos.org/pipermail/centos-devel/2008-June/002961.html
http://lists.centos.org/pipermail/centos/2008-July/060236.html

At any rate, you want to remove all *.i?86 packages and then add this line:

exclude=*.i386 *.i686

in /etc/yum.conf to maintain a pure 64-bit system.
