I'd say it's a side-effect of the approach we use -- if you upload a
kickstart profile, it will not contain the correct rhnreg_ks in
it to use the activation key, and in the pre-cobbler era we even did
not have snippets to somehow get it in.

I don't think you have. If the approach works in your tests, we'll
love to see a patch. ;-)
