Hi Sean.
I'm not entirely sure you can do the switch on the fly.
Vga_swticheroo docs states that we can't switch graphics cards while X is running, and of course, is not possible on Windows using the latest proprietary drivers. That's why I thought it was safer this way.

Anyway, if you want to try using an "on-the-fly" approach, you must change the DIGS and DDIS commands to IGS and DIS to try an immediate switch.

Btw, the power function stuff is very interesting. Never thought of what happens when I resume the notebook. I'll check out.
