It looks you encountered the same problem like Dennis. So the answer will be
Your Xorg log file says:
(II) fglrx(0): Supported additional Video Mode:
(II) fglrx(0): clock: 96.3 MHz Image Size: 367 x 230 mm
(II) fglrx(0): h_active: 1440 h_sync: 1504 h_sync_end 1536 h_blank_end 1760
(II) fglrx(0): v_active: 900 v_sync: 903 v_sync_end 906 v_blanking: 912
As you see fglrx knows about 1440x900 native resolution of your LCD panel.
You probably encountered something similar to "ATI known issue":
"Connecting a display device that supports 1680x1050 to a system running
Linux may result in a maximum display resolution of 1280x1024 only being
available" together with another "ATI known issue":
"Custom mode lines in xorg.conf may be ignored by the fglrx driver"
712_linux.html suggests that nothing can be done except waiting for next
fglrx release. I can not do anything with this bug. It is ATI's internal
bug in binary code.
It looks ATI has problem with handling big screens (those above industrial
standard of maxiumum 1280x1024)
