its a problem with how the X configuration tools are building the mode list.
1680x1050 is sorted as smaller than 1600x1200.   X server on start up
parses the mode list and see the 1680x1050 as the largest mode and
sets the virtual resolution to that mode.

config tools sort the modes by area... X seems to sort the modes by
width then height.
As a result X sees 1680x1050 as the largest mode in the list.  The
config tool functions in rhpl need to be corrected to do a mode sort
the same way X sorts the mode list. So that when you ask for 1600x1200
 the 1680x1050 mode will not be placed in the config file.
