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,
