If you feel a bit adventurous you can try whenever current git master
(or 4.5-rc1 when Linus releases it next weekend) as guest kernel works
for you.
Recent linux kernels seem to not require the host bridge tweaks any
more. A patch to recognize the qemu q35 south bridge has been added in
the merge window.
So using the q35 machine type + vfio passthrough without any special igd
tweaks has a fair chance to work. opregion support isn't there yet, so
don't expect laptop panels work correctly.
cheers,
Gerd
