Currently I have a 32-bit Solaris 8 install CD at work, and Qemu SPARC32 
by default emulates an SS-5 sun4m machine (which Artyom has managed to 
get working with a PROM image from a real SS-5). Hence I've been 
comparing outputs to try and figure out what the Solaris kernel is doing 
with OBP which we currently aren't doing correctly in OpenBIOS.

Yes thanks - I already have a copy of this in my PDF library :)
