make new Lubuntu versions cooperate with Pentium M

As far as I know, the solution proposed in the thread is not suitable
for everyone, because it sets the pae flag for every CPU, even the
ones which not supported pae.

The proper fix, if those CPU effectively support pae (which I'm not
very sure, regarding the speed issues reported some time on the
thread), is to report a bug on the kernel, so it can set properly the
pae flag itself.
