Thanx.  Can someone else verify that kqemu still works on FreeBSD-current?
It is possible that you got hit by the kqemu tsc vs smp problem, i.e.
passing `notsc' to the guest kernel or forcing qemu onto one cpu
(cpuset -l 0 qemu ...) may have helped there, sorry I should have thought
of that earlier...

 Also, did I get that right that this opensuse 10.3 install worked with
the original qemu-devel port (without kqemu)?  So we do seem to have a
regression here...  (thats a 20080620 qemu svn snapshot, for the folks
on the qemu list.)

 Thanx,
