<pre>After getting the system to a sane state post boot on a macbook pro 8,2, with
the DIS connected, IGD disconnected and off, turning on the IGD then performing
a switch fails with:
kernel: vga_switcheroo: client 0 refused switch.
No X server was running at the time, only TTY.
The dmesg output is attached.</pre>
