Bug#284581: WSXGA screen size missing in config (1680x1050)

[Duncan Thomson <sciuro@gmail.com>]

i don't have a ModeLine in my XF86Config-4 at all, i've simply added
"1680x1050" to the beginning of the Modes lines which are used.

unfortunately 1680x1050 doesn't appear to be a VESA standard size, i
can only find "GTF" ModeLines for this size of screen.  would that be
an acceptable substitute, or not?

cheers,
