Hi,

My machines (IBM ThinkPad T41, Type 2373-9EU) all claim to
be Pentium-M and do NOT support PAE according to the Ubuntu
boot message. I do have 2GB (the max without PAE) of DRAM
installed.

How much simpler is life with PAE-only support?

(Since that is the path that was taken, I am hoping that the
answer is very trivial to quantify since the work was done
and the code base reflects that change).

I understand moving ahead, but, to me, this fairly capable 32-bit
machine should still be supportable by Ubuntu.  I have not tried
using CentOS as my desktop yet, but maybe that is an option if
I can't get the next LTS (14.04) Ubuntu to boot straight up.

Cheers,
  --ldl
