Bug detailed description:
Using xrandr to start a external display, the external output failed to
switch to Text mode by "ctl + alt + f1". This issue also happens on 945GM and 965GM.

Reproduce steps:
1. boot machine 
2. connect a external display with VGA port
3. start up external output by cmd "xrandr --output VGA1 --auto"
4. switching to text mode by cmd "chvt 1" or "ctl + alt + f1"
5. only LVDS output switch to Text mode.

This is expected result, if you load i915 kms driver with vga attached, then later we can restore back the origin state of vga, otherwise we can't know.
