Hi!

 I've made another experimental FreeBSD qemu-devel port update,
	http://people.freebsd.org/~nox/qemu/qemu-devel-20090118.patch
and of the few things I've tested so far I only found vmmouse and -vga vmware
broken now, vmmouse leaves the mouse cursor stuck in the top left corner,
and -vga vmware causes a broken display at least with xorg's vmware driver.
(both of these worked at least with the r6082, 2008-12-18 snapshot as
posted in
	http://lists.gnu.org/archive/html/qemu-devel/2008-12/msg01417.html
)

 virtio and hpet still seem to work, and slirp indeed seems to finally work
on amd64 hosts.

 FreeBSD has a #define sigev_signo	__sigev_u.__sigev_signo
in <sys/signal.h> so I've had to patch it to something different in
the posix-aio-compat code:

 More tests welcome...
