the 'cvt' tool will build mode lines using the coordinated video timing
spec from VESA. Just give it the size (and optional refresh rate):

$ cvt 1680 1050
# 1680x1050 59.95 Hz (CVT 1.76MA) hsync: 65.29 kHz; pclk: 146.25 MHz
Modeline "1680x1050_60.00"  146.25  1680 1784 1960 2240  1050 1053 1059
1089 -hsync +vsync

The server has a lot of modes built in, so you can often get by by just
setting the horizontal and vertical refresh ranges.
