Nice cleanups, that function was getting too big...  misc nitpicks
below.

May as well fix the comment here or combine it with the above.  There
are a few other comments like this elsewhere too.

While you're in there it would also be cool to write a small CRTC mode
verification function that checks the htotal/vtotal/etc against the
constraints documented in the manual (e.g. sync before end, active
divisible by 2 in ganged mode, etc).  If you're feeling adventurous
anyway. :)
