make fbdev/fbcon switchable per driver?

Hi folks,
Problem at hand: A virtual machine, equipped with two display devices,
one virtual, one physical (using pci pass-through, or kvmgt-based vgpu).
There is no easy way for the user to configure which of the two display
devices fbcon should run on. i915 happens to win over bochs-drm or qxl,
so you can't use the emulated gfx device as text console.
One way out would be to add a module option to each driver, to turn off
fbdev emulation. Attached patch does that for i915.
Comments? Better ideas?
cheers,
Gerd
