xorg.conf which triggers this problem.

When booting Intel G45 graphics into a low res KMS mode (ie 800x600) and
starting an Xserver (using the native Intel driver) in a different low res mode
(for instance 640x480) the text console remains blank after terminating the
Xserver.

This issue can easily be reproduced with the attached Xserver config file:

1. Boot the machine into an 800x600 mode. This works with any monitor if the 
   command line option: video=VGA-1:800x600 is specified.
2. Once booted start an Xserver with attached config file.

When the Xserver terminates the probability that the screen remains blank is
high (> 90 percent).
