There should be a way to put the 8601a specific stuff in northbridge/via/8601a, and try and keep vga generic (legacy) register code in a central place (eg, pc80/). This worked well for stpc and sis630; most of the code is common even though the chips are radically different, they both match well to legacy VGA. There are also changes to lib/video_subr.c since it currently doesn't move the cursor or use the correct memory address for text.
The only reason this hasn't been integrated into linuxbios codebase at this point is partly lack of interest (I think) in this group, since most use the serial console, and partly that I have been off on other things lately.
All of my projects use the vga console, so as I use various integrated chipsets, I will be adding vga for each. Until this gets into the linuxbios base, anyone that wants the code just send me an email. It's all gpl of course.
I am working on getting the sis 530 working which on my Arbor PIA-671 board has a 630 3D AGP card I would mainly like to use for my project. So if you can send me the code to enable the VGA stuff that would be great. I do have the datasheet for the board and its video controller so I may be able to find the "special chip specific" stuff from looking at your code.
Thanks in advance,
