0. Maybe there's a non-PAE kernel that can be selected at Trisquel Mini's
bootmenu? (OK probably no)
1. What do you think about using netinstall instead (I hope its ISO comes
with a non-PAE kernel)?
2. You can look up "debootstraaping" on the net - wouldn't be easy, but I
think it's still rather learnable.
Anyway, if you REALLY want an old version of Trisquel (please don't, though):
http://oldarchive.trisquel.info/
(please note that if at any point in the future you're not able to install
anything from the repository - the repos need to be changed so that it goes
to http://oldarchive.trisquel.info/trisquel rather than something like
http://archive.trisquel.info/trisquel .
