The problem is that ATrpms supports kernels of F7, and there are kmdls
for each kernel rpm there is. So far so good. But once the kernel rpm
is deleted from the main repo suddenly yum sees packages that don't
have a kernel counterpart anymore. Technically correct yum tells you
that foo-kmdl-2.6.22.1-41.fc7 depends on the not-anymore-existing
kernel-2.6.22.1-41.fc7.

Now is it a problem in repos or in yum? I would say both. The 3rd
paryt repo, in this case ATrpms, can't react that fast to changes in
the master repo, not even the (two) kernel modules shipped in Fedora
themselves can. So for a short period of time there will be "broken"
dependencies.

Yum's "fault" is that it is too fragile against such changes, other
depsolvers like apt and smart are more forgiving. But there is a
plugin that makes yum behave like apt and smart called
"skip-broken-dependencies" plugin or similar. Desite its frightening
name I would recommend this as the default setup for any system.
