Dalibor, I'm quite surprised you didn't at least mention Kaffe, surely
this has a port to GNU/Linux + SPARC ;)

FWIW, as was said before, this seems like one of the easiest ports as
the two bits are there -- SPARC support for Solaris and GNU/Linux
support for x86 and x86_64, unlike PPC where the CPU side has had to
be implemented from scratch.
