kickstart %packages field currently only supports name entries for packages. it should probably support name.arch for the multilib machines where someone wants to install the compat arch libs.
Added in CVS with syntax name.arch on the remembering that that is the syntax with yum (if not, let me know and I'll change mine). Note that it requires exact arch matching.
Yay! Thanks Jeremy. Now will you add name,arch, etc specification to comps.xml, too. :) Boy I'm glad I can't be kicked from bugzilla.
