I am hoping to get standard alphanumeric vga setup into the linuxbios code
base, as part of the stpc initialization, in the very near future. Linux
assumes the vga registers are already initialized in vgacon.c (in
drivers/video), and changes only a few register settings. But (hopefully)
for alph

this is what is the case.
BIOS has notion of "extensions", which just piece of firmware on each

Unfortunately, yes.
The problem is that video BIOSes run in real mode and tend to rely on legacy
system BIOS services. These _can_ be rewritten but noone on this list is
very interested in doing so because it is a LOT o

see vgabios support in linuxbios. We can do that.

we already can do this, see the vgabios stuff.
