Does KVM work properly with PAE kernels at the moment?  I've had trouble
with it within the last six months, and when running server
installations I've had to tweak them on the fly to install the generic
kernel in order that I could boot the installed system.

I'd have thought we needed data here?  I'm worried about dropping the
kernel that's been the default during the installer for some time, in
one step.  If we want to switch the installer to generic-pae and then
drop the non-PAE kernel in the next cycle if that works out well, I'd be
happier with that approach; that gives us a much more graceful fallback
plan in the event that our opinions are mistaken.
