Ah, I think I see what the problem is. Since it didn't detect the monitor, it set the wrong resolutions up. This is a dupe of 3731 apparently.
Change your screen section to look like this:
Section "Screen" Identifier "Default Screen" Device "ATI Technologies, Inc. X700" Monitor "Default" DefaultDepth 24 SubSection "Display" Depth 1 Modes "1680x1050" EndSubSection SubSection "Display" Depth 4 Modes "1680x1050" EndSubSection SubSection "Display" Depth 8 Modes "1680x1050" EndSubSection SubSection "Display" Depth 15 Modes "1680x1050" EndSubSection SubSection "Display" Depth 16 Modes "1680x1050" EndSubSection SubSection "Display" Depth 24 Modes "1680x1050" EndSubSection EndSection
Alternately, install and run displayconfig-gtk as root, and test out correcting the resolutions through that GUI tool. We'll probably be having people use this approach for fixing these resolution issues from now on.
