So just show the
packages for the installed architecture and the noarch packages! the
rest is really not of any interest for most users! Or add a filter to
only show the packages of your architecture.
look at this http://www.packagekit.org/pk-matrix.html scroll down to the part for filters. It seems the architecture thing is not supported because of yum. Or does it? I don't know enough to comment. Mayb someone can enlighten on this?
