There are no limitations in the hw with respect to modes for the most part. 
Try removing the monitor and modes sections in your config.  your monitor
provides an edid so you should be getting all of the montior's supported modes
via the edid.  Also, don't use xrandr -s.  That's a randr 1.0 command and the
backwards compat code in the xserver doesn't always do the right thing since
xrandr 1.2 support multiple outputs.  use:
xrandr --output DVI-0 --mode <mode name>

Please post your new xorg log and config after remving the monitor and modes
sections if you are still having trouble.
