Hi Iberê,

Your Celeron M 1.2 GHz is maybe a couple of years older than my Pentium
M with 1.7 GHz. It would be very valuable for the project to know, if
your CPU has the PAE capability, and I think the best way to find out is
to try. We can only guess from what we find on the internet ;-)

Have you looked at

https://help.ubuntu.com/community/Lubuntu-fake-PAE

yet? It is still in 'beta state', the image and instruction (README)
files reside on my google drive page. Please look at it in more detail!

You need not touch your working Lubuntu 12.04. Make an install USB
pendrive with 'grub-n-iso' (or a portable 'installed system' if you have
a 16 GB pendrive). Just make sure you are cloning the image to the USB
pendrive, and not to the internal HDD.

I would be very happy if you can try it and report the result.

When I run Lubuntu 12.04 with a non-pae kernel

cat /proc/cpuinfo

reports 32 bits for my Pentium M,

but when I run Lubuntu 13.04, it reports 36 bits physical address size.

So you need the pae kernel running to get 36 bits. If you don't get 36
bits, your celeron M 1.2 GHz has no PAE capability. At least this is
what I understand.

Best regards
Nio
