When I use this startup script:
xrandr --output DVI-0 --primary --mode 1920x1200 --left-of HDMI-0
xrandr --output HDMI-0 --mode 1920x1080
xrandr --output VGA-0 --mode 1680x1050 --above DVI-0
xrandr --dpi 108

things improve dramatically. 1920x1080 appears right of 1920x1200, and mouse can
reach them both, but 1680x1050 remains asleep.
Xrandr and Xorg.0.log combined:

Is this low-budget Sapphire ATI Cedar gfxcard not supposed to be able to produce
on all three outputs at once?
