There's some info about installing Debian 5 (?) on Peg 2 here:

I've got a Quad boot of OS4.1/MorphOS/Debian/Suse, But it was so long ago, I've forgetten how I did it

I don't use Linux much and SUSE less than Debian, probably due to the early version of KDE4, and I never got around to updating it, if that was even possible.
