When did this happen? This is good. Now we can potentially make
the textmode-only KGI in-kernel mini boot display driver run completely on
top of fbcons.c, which in theory would port KGI to any Linux/xxx which has
fbcons support! Of course there is some other VGA-specific stuff in KGI
but that can be gotten around with #defines or what have you.

VGA-style textmodes are a historical anomaly. Better to design
around software textmodes as an abstraction and just map it onto whatever
HW you have.
