This is what was done prior to the big refactor in kernel 3.8, and what was done by xf86-video-nv. Experimentally, it seems like there's some sort of issue with the high-res lut to be used there. Tested on G92. This ends up mattering because fbcon/fbdev chooses the C8 fb format for low-vram systems, which can occur with some IGP-based configurations with little "stolen" vram.

Hi! While trying to get CLUT support for the atmel_hlcdc driver, and specifically for the emulated fbdev interface, I received some push-back that my feeble in-driver attempts should be solved by the core. This is my attempt to do it right. I have obviously not tested all of this with more than a compile, but patches 1 and 3 are enough to make the atmel-hlcdc driver do what I need. The rest is
