I took a snapshot from xen-unstable and applied those patches.
However when trying to create a HVM domU the following error comes up:
# xm create test2.xm
Error: local variable 'str' referenced before assignment
Using config file "/etc/xen/test2.xm".
And xend-debug.log gives some more info:

UnboundLocalError: local variable 'str' referenced before assignment
Is this error related to the patches or is something else broken? I have
to admit that I've not been using xen-unstable for some time, only
release-3.4.1 and recently Xenclient, so I don't know if this is also a
problem on unpatched xen-unstable.
The error disappears when I omit the "pci=" line, but obviously this is
not a good scenario to test gfx passthrough ;-)
My config file for the test-domU:
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 4096
name = "TEST2"
vcpus=8
vif = [ 'type=netfront, mac=00:16:3e:ff:ff:22, bridge=eth0' ]
disk = [ 'phy:vgtest/test2,xvda,w' ]
#viridian = 1
device_model = '/usr/lib/xen/bin/qemu-dm'
#boot="cd"
#sdl=0
#opengl=0
#vnc=1
#vnclisten="127.0.0.1"
#vncdisplay=1
#vncpasswd=''
#stdvga=0
gfx_passthru=2
pci=['03:00.0']
Thanks,
