[PATCH] add modeline for 1680x1050@60

[Olaf Hering]

Add a modeline for the Philips 200W display. 
aty128fb does not do DDC, it picks 1920x1440 or similar.
It works ok with nvidiafb because it can ask for DDC data.

What happens if you use something like

video=atyfb:1680x1050M@60; or
video=atyfb:1680x1050MR@60
