Since I already made an experimental FreeBSD qemu-devel port update
for 0.11.0 rc1 updating that to 0.11.0 rc2 was easy:

(I changed two things tho, see below.)

 This seems to work well, I now can run a Linux iso with -vga vmware
and vmmouse and set all kinds of resolutions in the guest using xrandr.
Thanx!

 Ok now what I changed:  I removed the dynticks patch since it seems to
perform even worse than -clock unix on FreeBSD (does this count as a
qemu bug?  The problem seems to be that FreeBSD's POSIX `realtime'
timers still only count in increments of HZ, and then seem to always
round up too.)  And -clock unix is only marginally better, see
my post here:
	http://lists.gnu.org/archive/html/qemu-devel/2009-09/msg00049.html
(well at least its good enough that Linux guest kernels don't fail to
boot like with -clock dynticks.)

 The second change is a small patch to tap_cleanup that makes it close
the tap fd before calling the ifdown script instead of after, otherwise
FreeBSD's tap driver may hit a KASSERT in case the ifdown script does
something like an `ifconfig tap0 destroy'...

 I don't know if there are use cases where the ifdown script needs the
tap fd still open, otherwise I guess this can also be committed upstream.
And in case you want to: :)
