I have no problem with doing this in the driver, as long as every driver
does it the same way. The drivers will be doing the work anyway.

The complicated bits would be when both screen have not the same
resolution. Altough i get using a virtual screen is the way to go, i
have doubts that the current desktop manager will understand that we are
not using a part of the screen.

Funny that there is discution about this in the DRI list, while when i
asked on the xfree86 list some time ago, nobody cared.
