If it *is* /just/ PAE that is the issue, then non-PAE CPUs were
supported in the mainline distro until 11.10 and could be installed
with 12.04 using the mini-netboot ISO followed by a manual install of
the desktop environment:

apt-get install ubuntu-desktop -y
apt-get install lubuntu-desktop -y
apt-get install xubuntu-desktop -y

... etc.

N.B. that Lubuntu 12.04 is *not* an LTS release.

However, if the Via C3 has other issues as well as PAE support, this
may not be enough.

If you are running 12.04 successfully and want to /upgrade/ to a newer
release, you can do this using a small tweak that fakes PAE support:


I have tested this successfully with Lubuntu 12.10 and 13.04 on an IBM
Thinkpad X31 with a 1.7GHz Pentium-M CPU, which is more than fast
enough to run Lubuntu very well but lacks PAE. (It is *considerably*
quicker than an Atom CPU of equivalent MHz which has PAE.)
