This really requires building another layer of sophistication into the
drivers. Basically the driver would need to understand the concept of
doing modesetting on one GPU but (when appropriate) doing acceleration
on the other GPU. 

Add Compiz to the mix and it gets exciting ;)

OK, I was hoping that maybe the docking station internals would allow
the new graphics card to appear as another PCI Express device on the
bus, and then the driver could somehow connect the LCD panel to it
purely through configuration.

Trust "reality" to be slightly more complicated. Probably with a
performance penalty too.

Cheers,
Chris
