Here is my partition layout, done thru MorphOS first..

31k apple
60mb HFS MorphOS boot files
120GB SFS "DH1" where MorphOS is installed (and all my other stuff. I put it all in 1 partition)


So What I did first was install MorphOS. What you see up there is what I had before Debian.

I was left with 115GB or so free. So I used Guided in Debian and selected "largest free space" or something like that.

Once that was done and installed, MorphOS no longer booted as expected. Then edit yaboot.conf, update it while in Debian as previously posted in this thread. Then you're all set.

EDIT:
On my setup I find MATE to be the fastest and most responsive. When I drag Iceweasel it drags slow..with MATE, almost instant.
