Cool :)

If you have good document describing what solaris boot loader
expects from open firmware, that would really help. I have
of1275.pdf and it's 32bit and 64bit bindings, and these do not

really means.

There are still issues with qemu emulation code, but we are
making some progress :) My plan is to first have ultrasparcIIi
qemu emulation booting linux to userspace using openbios
sparc64 prom.
