yep, the only other one is armmp-lpae, but that only adds a couple more
configs, the rest are all meta-packages.

Thought about that, but that would probably cause havok in case the
driver is actually ran in a VM on top of Xen, wouldn't it (however
unlikely that might be)? It won't fail to load anymore since we don't
support it, and probably die later. Nonetheless, I'll give it a shot and
see how it behaves later tonight or tomorrow.
