If you know the author you can simply ask to use the code as well.
Paul Mackerras of Linux-pmac fame has given me permission to refer to his
code for the Valkyrie video driver so I can write a driver for the 630.

It was sort of the reverse situation to the IDE. I figured out the controller
and DAC base but I only had a little bit of knowlege about the chips :-)
It's a good thing, too, because the timing is controlled via the CUDA.
Paul had to use a scope to find the values! So it certainly has saved me
time reverse engineering the hardware!
