You can always rebuild your own rpms too ;>  All you need to do is
specify the optimizations for your arch in /usr/lib/rpm/rpmrc
(optflags:).  Check out the gcc or even Gentoo pages for optimization
info, they tend to be very particular about this sort of thing and can
give you lots of insight.

Once this is set, for say "athlon", just uncomment the "rpm-src" line
for planet in your sources.list and do:

apt-get update
apt-get source $PACKAGE_NAME
rpmbuild --rebuild --target athlon $PACKAGE_NAME.src.rpm
rpm -ivh /usr/src/redhat/RPMS/athlon/$PACKAGE_NAME.athlon.rpm

Somone could easily script a complete athlon planet in this way :)
