There is another bug, using pci_default_write_config() doesn't fly as
this checks writes against wmask and the registers in question are not
whitelisted ...

I've just rebased my igd patch series which (among other stuff) fixes
that bug:
  https://www.kraxel.org/cgit/qemu/log/?h=work/igd
  git://git.kraxel.org/qemu work/igd

Can you give it a spin?

Also: what does "can't boot up" mean exactly?  Guest doesn't boot at
all?  Guest boots, but igd/console/Xorg doesn't work?  In case of the
latter:  Any chance to login via network and get a kernel log?

thanks,
  Gerd
