It was decided not to drop the non-pae kernel flavour until 12.10, so 
that non-pae computers would still be supported for five years.

I happen to have one of these, I use it on a daily basis for IRC and a 
few other things. So now I want to test 12.04 on that laptop, but when I 
try to boot the daily live-CD, I get an error saying that my CPU is 
missing the pae feature.

How can I install 12.04 on my non-pae kernel when I can't boot the 
installer? Am I missing something?

(Btw, I didn't test the alternate installer, but looking at the file 
listing for the alternate install CD, it seems to have the pae kernel as
