The required interfaces are now available in mainline. [1] I rebuilt to
make sure it compiles.

Besides bochs, [2] the patches for qxl, [3] cirrus, [4] vmwgfx, [5][6]
and virtio [7][8] should now build as well. They still apply cleanly
AFAICT. Let me know if you prefer a new patch set instead.

Best regards
Thomas
