Maybe I'll focus on trying to track down the source of some of the other error messages that seem to contribute to not being able to boot 64-bit Solaris - particularly Solaris 10 and higher, since I think that's where the CPU Power Management starts, which would be great to get working for the CPU performance aspect of running Qemu.

Gah. Sorry Nick - this message was definitely a case of "fingers before 
brain. What I meant to say was that I see the "VAC too big!" error on my 
local copy of *64-bit* Solaris 9 too. I currently don't have access to a 
Solaris 9 32-bit image for testing, but it sounds as if it is working 
fine for you which is great.


ATB,

Mark.
