i945: can't get triple head to work

[Tomasz Torcz]

  Hi,

 I have a laptop with Intel chipset:
00:02.0 VGA compatible controller: Intel Corporation Mobile
945GM/GMS/940GML Express Integrated Graphics Controller (rev 03)

 I'm using Ubuntu with unofficial Intel driver version 2.0.0-1feisty1.
xorg.conf is almost without any options, only "Virtual 2048 2048" is there.
I've connected external LCD (via VGA) and TV and can't get them to work
simultanously with built-in display.

xrandr shows:

Screen 0: minimum 320 x 200, current 1440 x 900, maximum 2048 x 2048
VGA connected (normal left inverted right)
   1280x1024      60.0 +   75.0     59.9  
   1152x864       75.0  
   1024x768       74.9     75.1     60.0  
   832x624        74.6  
   800x600        75.0     74.9     60.3  
   640x480        75.0     74.8     60.0  
   720x400        70.1  
LVDS connected 1440x900+0+0 (normal left inverted right) 303mm x 190mm
   1440x900       60.0*+   50.0  
   1280x800       60.0  
   1280x768       60.0  
   1024x768       60.0  
   800x600        60.3  
   640x480        60.0     59.9  
TV connected (normal left inverted right)
   1024x768       30.0  
   800x600        30.0  
   848x480        30.0  
   640x480        30.0  

  I can enable LVDS+VGA or LVDS+TV or VGA+TV. But when I have enabled
two of them, enabling third do not work:

(when LVDS and VGA are active)
% xrandr --output TV --preferred
xrandr: cannot find crtc for output TV

(xrandr --auto yields same result).

When LVDS and TV are active, messages says "xrandr: cannot find crtc for
output VGA". Is this fixed in later version of driver?
