gfx card passthrough broken with latest head

["André Weidemann" <Andre.Weidemann@web.de>]

Hi,
I pulled latest git yesterday and noticed that graphics card pass 
through does not work anymore. The VM hangs (probably when initializing 
the gfx card) when passing a graphics card to the VM.

I started to do a git bisect but device assignment does not work at all 
when doing it.

I started like this:

cd /usr/local/src
git clone git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git 
qemu-kvm-2011-08-12
cd qemu-kvm-2011-08-12
git bisect start
git bisect good fda19064e889d4419dd3dc69ca8e6e7a1535fdf5
git bisect bad 44755ea36fee3f0b1093ef27404def8857602274

Bisecting: 229 revisions left to test after this
[55c0975c5b358e948b9ae7bd7b07eff92508e756] Do constant folding for shift 
operations.

./configure --audio-drv-list=alsa --target-list=x86_64-softmmu 
--enable-kvm-device-assignment

ERROR: unknown option --enable-kvm-device-assignment

What am I doing wrong?

Regards
