Well, the good news is that at least for the gfx registers, I actually 
have a proof-of-concept script that extracts the required information 
from the hardware sources. Generating e.g. a CB_COLOR_INFO(x) macro 
instead of CB_COLORx_INFO defines from that is not that hard :)

The real challenge is getting this integrated into the right processes 
so we don't have as much of a maintenance burden.

Cheers,
Nicolai
