Ah, yes, it's not specified well enough. So I guess it should actually
be two parameters:
 device path - whatever we are calling it nowadays.
 device specific monitor number (or frame buffer id).

This should be good enough for current 4 pci qxl devices, and future
proof for a single qxl with multiple monitor outputs. Same goes for
s/qxl/any other framebuffer device/, I'm just not sure which are there
(although I'll find out a little by trying out the arm emulater for the
r-pi).
