I agree Julien,

that the fake-pae fix in the ubuntuforums thread is not for everyone,
but I think it would be fairly easy to enter some logic to make a
difference between the Pentium M CPUs, that support pae, and the other
non-pae CPUs. I can make such logic statements, but I need help to find
where to put them. (Before retiring, I used to make computer models of
physical processes.)

By the way, I think the only computers without pae, that are useful for
anything but 'retro playing', are laptops with Pentium M. And, I think
the main objective is not to stuff those old computers with more than 2
GB of RAM to exploit the pae feature, but to be able to run a new
Lubuntu version at all with the memory available, often around 1 GB.

Do you mean that reporting a bug is the correct way to continue? I mean,
it's not really a bug, it is an improvment, like a new feature. But if a
bug report is the way to find the gal/guy, who could help me with the
programming, or whom I could help with the programming and testing, I'll
do it.

     -o-

But I'll wait for confirmation, so if anyone reading this wants to
encourage or discourage this, please do now :-)

Best regards
Nio
