Last version with some changes according to review and adding more
patches. The patch adding i2c support to CUDA is not yet working, only
included here as RFC and show direction but any help fixing it is
welcome as I've run out of free time for this. I think with i2c
support fixed (and maybe adding real screamer implementation) could
get us somewhere with the firmware ROM. Once it starts poking a video
card I'm willing to look at what ati-vga may need to work with this
but help is welcome getting to that point.
