Not exactly simple, but I manage it by creating i386 repo definitions
that are disabled by default and enabling them with 
"yum --enablerepo=reponame update <packages>" (or "install").  Works OK
once you get the right set of 32-bit packages installed for browsers,
etc.

Here's my current set of CentOS4 browser-related packages for a dual
Opteron:

acroread-7.0.0-2.rf.i386
firefox-1.0.6-1.4.2.centos4.i386
mozilla-1.7.10-1.4.2.centos4.i386
mozilla-acroread-7.0.0-2.rf.i386
mozilla-chat-1.7.10-1.4.2.centos4.i386
mozilla-devel-1.7.10-1.4.2.centos4.i386
mozilla-dom-inspector-1.7.10-1.4.2.centos4.i386
mozilla-js-debugger-1.7.10-1.4.2.centos4.i386
mozilla-mail-1.7.10-1.4.2.centos4.i386
mozilla-nspr-1.7.10-1.4.2.centos4.i386
mozilla-nspr-1.7.10-1.4.2.centos4.x86_64
mozilla-nspr-devel-1.7.10-1.4.2.centos4.i386
mozilla-nss-1.7.10-1.4.2.centos4.i386
mozilla-nss-1.7.10-1.4.2.centos4.x86_64
mozilla-nss-devel-1.7.10-1.4.2.centos4.i386
mozilla-nss-devel-1.7.10-1.4.2.centos4.x86_64
