oh, man, great idea! I always forget this because with linuxbios vga is 
the last thing you get. 

Attached is a (short) piece of code we used to use for this purpose, when 
we were doing early work.

It is so short I hope the list does not mind -- others of you might find 
it useful too. We got a lot of use out of it. 

In video_init, just comment ou the vga_hardware_fixup(). Also vidmem 
should probably be set to B8000. 
i.e. 
static char *vidmem = VIDBUFFER;
