VmWare only works on x86 boxen. Sorry.

Usermode linux purports to do what you want, though I've never tried it. 
Don't use Bochs because it will be horrendously slow.

You could just use a chroot, I guess. But then since others might have root, 
that's maybe not such a good idea (unless you further restrict the chroot 
with a grsecurity kernel). You would be able to then boot this chrooted 
system normally if you use another partition for it.

Of course, the most fun thing to do would be to trash the Debian system :o)
