I have a laptop with i945 graphics. Any reason why the screen would be
limited like it seems to be:

continuity> xrandr
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1280
VGA connected (normal left inverted right)
   1280x1024      75.0     59.9  
   1152x864       74.8  
   1024x768       75.1     60.0  
   800x600        75.0     60.3  
   640x480        75.0     60.0  
   720x400        70.1  
LVDS connected 1280x800+0+0 (normal left inverted right) 261mm x 163mm
   1280x800       60.0*+   60.0  
   1280x768       60.0  
   1280x720       60.0  
   1024x768       60.0  
   800x600        60.3  
   640x480        59.9  
TV disconnected (normal left inverted right)
continuity> xrandr --output VGA --mode 1280x1024 --pos 1281x0
xrandr: screen cannot be larger than 1280x1280 (desired size 2561x1024)
continuity> xrandr --output VGA --mode 1024x768 --pos 1281x0
xrandr: screen cannot be larger than 1280x1280 (desired size 2305x800)
continuity> xrandr --output LDVS --mode 1280x800 --output VGA --mode 1024x768 --pos 1281x0
xrandr: screen cannot be larger than 1280x1280 (desired size 2305x800)

I connect up a Dell 2407 LCD display which doesn't seem to be correctly
detected (1920x1200 native resolution) and then my max resolution
doesn't seem to allow for much expansion. I thought the driver would
borrow system memory as needed (so that this is not a memory problem)?

Thanks,
