Hmmm... where would you plug it in?
I wasn't aware that you could replace the video mode set routines
in the BIOS with code from another ROM, as you do with drivers, etc.
Just where does syscons.c start functioning in the boot process? What
messages would you see if you just hacked the starting mode in the
syscons.c file to work with the fixed-freq monitors? Would you only
miss the AMI BIOS messages about system config?
