What seems to be the problem? The monitor's preferred mode is 1280 by
1024 and the physical size is according to the edid from the monitor:
II) RADEON(0): Supported additional Video Mode:
(II) RADEON(0): clock: 108.0 MHz Image Size: 317 x 254 mm
(II) RADEON(0): h_active: 1280 h_sync: 1328 h_sync_end 1440
h_blank_end 1688 h_border: 0
(II) RADEON(0): v_active: 1024 v_sync: 1025 v_sync_end 1028
v_blanking: 1066 v_border: 0
