I saw that there was some xrandr work done recently.

Here is what xrandr reports on the default alpine linux
xf86-video-openchrome package (trunc -r921 iirc):
Screen 0: minimum 640 x 480, current 1280 x 768, maximum 1280 x 768
default connected 1280x768+0+0 0mm x 0mm
   1280x768       60.0* 
   1280x720       59.0  
   1024x768       70.0     60.0  
   1024x600       59.0  
   1024x576       60.0  
   1024x512       60.0  
   800x600        60.0     56.0  
   720x576        60.0  
   856x480        60.0  
   848x480        60.0  
   800x480        60.0  
   720x480        60.0  
   640x480        60.0  

And here is what xrandr reports with kms_branch r977:

Screen 0: minimum 320 x 200, current 1280 x 768, maximum 2047 x 2047
LVDS connected 1280x768+0+0 (normal left inverted right x axis y axis)
0mm x 0mm
   1280x768       59.8* 
VGA disconnected (normal left inverted right x axis y axis)

VGA port was detected! Very nice!

I was able to connect it to a 1680x1050 screen, disable the LVDS and
enable the VGA with xrandr. Switching back to LVDS gave me the login
screen again (i suppose Xorg segfaulted). Running the VGA as --left-of
didnt work very well either. The screens were parially overlapping and
the image was scambled. (I had to use 640x480 on vga since this chip
does not support more than 2047 x 2047) Trying VGA --below made the
LVDS go blank.

We are moving forward! Thanks!
