Solaris support is horribly broken in 2.0.xx, don't expect it to actually
work. I've tried to rewrite support in 2.1.xx from scratch, but at the moment it is
for sparc64 only, though could be easily backported to sparc32. Networked
programs don't work yet though. My friend is now hacking on getting
networked programs (read streams) running.
There are some more issues to be solved, like the namei remapping
stuff /usr/gnemul/xxx/ is broken as hell, needs to be redesigned.

You can try some of the ftp.kernel.org/pub/linux/kernel/davem/
kernels, but latest the BEFORE_MEGAMERGE, as right now neither
sparc32 nor sparc64 will actually work (due to RTSIG changes).
I'm trying my best to get that working ASAP.

Cheers,
