[Qemu-devel] experimental FreeBSD {k,}qemu port update

[Juergen Lock <qemu-l@jelal.kn-bremen.de>]

Here is what I have tested on i386 with kqemu.  I also tried
-kernel-kqemu with a few linux 2.6 guests but only got panics, one
screenshot of KANOTIX-2006-CeBIT-RC3.iso is at
http://www.mytempdir.com/562050 (all panics looked like that).

 As amd64 guests with kqemu/amd64 are not supposed to work yet
I think we can't update the port yet, so i only post the following
for ppl wanting to experiment...

 First the patch for emulators/kqemu-kmod, after that after XXXX
the patch for the qemu port, updating it to today's cvs snapshot:
