Well, it's more than VGA on/off... if your card decodes VGA, then it's
all memory (or IO) resources on/off...

I -think- it may be that I split memory and IO with the idea that DRM
mostly don't need IO for irqs etc... and so we could technically steal
only IO for some things, like VGA based mode switching on the other
card, without disturbing the guy next door.

Cheers,
Ben.
