Title:
do-release-upgrade from Ubuntu 12.04 on Pentium-M fails, breaks system
without any warning (This kernel does not support a non-PAE CPU)

Bug description:
Attempting to upgrade from Precise with a non-PAE kernel will result
in a failed upgrade. do-release-upgrade should check whether the user
is using a non-PAE kernel and refuse to run, rather than upgrading to
a broken system with no installed kernel.
After downloading 1.5GB+ of data and over 1000 new packages, the
upgrade will eventually report failure. Looking through the logs there
is no kernel installed because of the error "This kernel does not
support a non-PAE CPU.":
