Your monitor's edid is the problem.  It's limiting the modes since it specifies
a max pix clock of 110 Mhz and the pix clock of the 1280x1024 mode is 135 Mhz:

(II) RADEON(0): 1280x1...@75hz
Modeline "1280x1024"x0.0  135.00  1280 1296 1440 1688  1024 1025 1028 1066
+hsync +vsync (80.0 kHz)
Ranges: V min: 50 V max: 120 Hz, H min: 30 H max: 72 kHz, PixClock max 110 MHz

To override, you need to specify the modeline for the preferred mode in your
xorg.conf monitor section, e.g.,:

Modeline "1280x1024"  135.00  1280 1296 1440 1688  1024 1025 1028 1066 +hsync
+vsync
Option "PreferredMode" "1280x1024"

You can also manually add the modeline at runtime with xrandr:
xrandr --newmode "1280x1024"  135.00  1280 1296 1440 1688  1024 1025 1028 1066
+hsync +vsync
xrandr --addmode VGA-0 "1280x1024"
xrandr --output VGA-0 --mode "1280x1024"

If the 1280x1024 mode works, then we probably need an edid quirk for your
monitor in the xserver.
