	It just replaces drivers/kernel/i386.c with fbcon-kgi.c.  It also
makes a few naming changes, and the kernel part of KGI (consoles and input
drivers) have been removed.  I am assuming that when your new KGI is
operational, we will somehow merge kgicon and KGI-Degas.  Should be
interesting....

	The kgicon drivers are just Dali drivers with a few tiny
modifications.  "Porting" should be trivial.  I used Dali drivers because
they already worked and I needed a working base to build fbcon-kgi on top
of.  Wait until Steffen is done with Degas/KGI and kgicon has been merged
with it to do any further porting.
