And this breaks upgrades, hopefully this will be fixed so upgrades get
blocked before systems get broken, see bug #1160346 ("do-release-upgrade
from Ubuntu 12.04 on Pentium-M fails, breaks system without any
warning")

The technical discussion was at
http://ubuntu.5.x6.nabble.com/Dropping-i386-non-PAE-as-a-supported-
kernel-flavour-in-Precise-Pangolin-td731288i20.html - the conclusion /
ultimate reason for dropping was:
"Dropping this flavour saves 5 minutes per build on a 4-way 80 thread
server, which for some of the team can add up to quite a bit of time
over the course of a day. Its one less variant that needs to be tested
in Q/A, and its one less flavour we have to mess with in our meta and
LBM packages. "
Also noted in same discussions on lubuntu list was that Ubuntu only
targets a 3 year hardware support window, so any hardware older than 3
years can be dropped. Ubuntu is not a distribution for old hardware.
Whether it was a good decision or not is a moot point now, it is done,
and for a Pentium-M user it is easier to choose a distribution that
still supports that CPU rather than try to install a distribution that
does not.
> So if this truely is about support, then stop supporting the 32 bit
architecture.
I am sure it is being considered for the same reasons, Apple already
dropped 32-bit, and Windows 8 will be the last 32-bit release.
