* CG6 display registers. (Note, I got tired of writing `cgsix' about
* halfway through and changed everything to cg6, but I probably missed
* some. Unfortunately, the way config works, we need to spell out `six'
* in some places anyway.)
*
* The cg6 is a complicated beastie. We have been unable to extract any
* documentation and most of the following are guesses based on a limited
* amount of reverse engineering.
*
* A cg6 is composed of numerous groups of control registers, all with TLAs:
* FBC - frame buffer control?
* FHC - fbc hardware configuration / control? register (32 bits)
* DHC - ???
* TEC - transform engine control?
* THC - TEC Hardware Configuration
* ROM - a 64Kbyte ROM with who knows what in it.
* colormap - see below
* frame buffer memory (video RAM)
* possible other stuff
*
* Like the cg3, the cg6 uses a Brooktree Video DAC (see btreg.h).
*
* Various revisions of the cgsix have various hardware bugs. So far,
* we have only seen rev 1 & 2.
