OpenSolaris.org has a kqemu version that I've been happily using there  
with SVN. It supposedly supports Solaris 9 and 8, so by inference 10  
as well, I'd hope.

Last time I heard it wasn't merged upstream, so it would be good to  
check how well the Solaris (and FreeBSD?) kqemu variants work with  
this series. Maybe merge into the current codebase before making too  
much assumptions for the new accel interface?
