Outouts atached to the card usually (there are cases where they do not) 
output the Cards Graphics. This is what Virtual OS gaming setups 
leverage to display the Windows Graphics of Games.

Passthrough for graphics cards has been working for people. If the 
Drivers (looking at you Nvidia) allow the card to run.

I am trying to discover how it might be possible to pass the console to a Zone that might be running a guest Bhyve and some how work out to have the guest OS using the console instead to the Global Zone.  This is not really the same as using zlogin in text mode but I do not have a complete picture in my mind on what might be, or not, achievable from the kernel perspective.
