Please don't. This patch fails to link for me in -rc5 - the errors start like

drivers/built-in.o(.text+0x18b): In function `vgacon_deinit':

and go on for another couple hundred lines.

IIRC, I found fixes for these when I merged this into my tree. It's a nice
addition, but there are aspects of this that I don't like, which is why I
haven't sent it in myself. Again, IIRC, enabling this disables the normal
consoles, which is fairly unfriendly.
