Well yes. You're making the user do something clever because the repo
has done something dumb.

Totally.

Sure. Either we do this in the yum plugin or we handle this in the
yumBackend.py file.

No, if a user can't be applied then it shouldn't be shown in the package
update list. The update list shows "updateable" packages.

kernel - get all the info - and then just install this specific update.
I don't think check boxes are the way to go at all.
