Bug#439322: xserver-xorg-video-ati: xrandr does not detect VGA monitor

[Marcus Better <marcus@better.se>]

The "monitor-S-video" option didn't work. I just got 

(II) RADEON(0): Output S-video using monitor section TV Monitor
(**) RADEON(0): Option "Ignore" "true"
(II) UnloadModule: "ati"
(II) UnloadModule: "int10"
(II) Unloading /usr/lib/xorg/modules//libint10.so
(II) UnloadModule: "vgahw"
(II) Unloading /usr/lib/xorg/modules//libvgahw.so
(II) UnloadModule: "radeon"
(EE) Screen(s) found, but none have a usable configuration.

Also the list of modes detected for the VGA monitor is missing the natural 
1280x1024 mode:

~$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 2304 x 1024
VGA-0 connected (normal left inverted right x axis y axis)
   1280x800       60.0
   1280x768       60.0
   1024x768       60.0
   800x600        60.3
   640x480        59.9
LVDS connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 
0mm
   1024x768       60.0*+
   800x600        60.3
   640x480        59.9
S-video disconnected (normal left inverted right x axis y axis)

This is an LG L1950SQ, a 19" LCD monitor, that supports 1280x1024.
