It works on Linux, but not on Windows. It is most likely a driver bug,
but nobody so far found a solution.

Using windows kernel debugger, the only "interesting" message I could find is:

"VIDEOPRT: Multifunction board not allowed to start"

(I compared windows kernel log of various pnp/pci/video mask with and
without multifunction qxl, it didn't help me to find why windows
refuse to start it)
