Alternative GCs for Kaffe ?

I did some playing around with an early version of kaffe (0.56 or something)
Boehm GC (formerely known as PARC GC). Adapting that version of Kaffe to
Boehm GC was pretty straight forward, I think it took me one or two days to
get everying (including finalzers and stuff) to work. From what I remember,
the only tricky part was to make Boehm GC to recognize the "pseudo-thread"
stacks allocated by kaffe.
I think I still have the code somewhere, but as I said, it was written for
an almost archaic version of kaffe. If you're interested, drop me a note.
