The synthetic driver can only take control of the synthetic video, but not
the emulated video.

Please add this to the comment above.

Actually, we already have a similar mechanism in ata/ata_piix.c to disable
emulated IDE drive on Hyper-V, so it won't conflict with the synthetic drive.

I havent read the vesafb code, but I think it can kind of give up the
hardware, something ata_piix can not do.
