Re: [Linux-fbdev-devel] setcolreg vs. 565

Well, X fbdev driver can only do truecolor afaik. It does send a
linear gamma table to the driver which is required anyway as the
fbdev themselves can be directcolor, but for real directcolor
support in X, we would probably need some other changes.

So for 5:6:5, doing only truecolor (and hard coding a linear ramp
in the chip's LUT) would do the trick for now. MOL can use gamma too
but it doesn't do 5:6:5, so it's a non-issue.
