Of course it's possible. Anything is possible in software :-)

And who calls the code in drivers/video/cfb_console.c ? I think this
is the drv_video_init() call in common/devices.c, right?

If this should be the highest level  in  the  call  chain,  then  any
conditional  calling should be done here. But - don't we already have
a board_video_init()  which  could  return  proper  status  to  abort
initialization?

Best regards,
