You've switched driver versions since your last email.  those options
only apply to ati master and 6.6.193 (mergedfb).  the logs you've
attached this time are from the xrandr-1.2 branch.  Using the
xrandr-1.2 branch you can force the vga output on using xrandr.

e.g.,
xrandr --addmode VGA-1 1360x768
xrandr --output VGA-1 --mode 1360x768
