Assuming that the monitor will talk to you, you should be able to get 
those by looking at the DDC info in the logfile, from X -configure,
or by running /usr/sbin/ddcprobe.

If the monitor isn't being friendly, here is the VESA GTF standard 
compliant mode that "gtf 1680 1050 60" reports:
  # 1680x1050 @ 60.00 Hz (GTF) hsync: 65.22 kHz; pclk: 147.14 MHz
  Modeline "1680x1050_60.00"  147.14  1680 1784 1968 2256  1050 1051 1054 1087  -HSync 
+Vsync
(This uses default flyback ratios: digital screens can get away 
with smaller "porches", so this may not match what your monitor
reports via DDC).
