Something like this can also be done for vgacon. I haven't added that yet.

This would be really nice. We had this discussion some time ago but
nothing was resolved. Basically we have to develope a way to define what
composes the framebuffer in a generic way. Something like fb_bitfields
plus a flag to say what it is. This would break things tho. I guess it
will be for the fb filesystem for 2.5.X.
