I had posted an excerpt of lshw output, and it was saying:

           *-display
                description: VGA compatible controller
                product: GK208GLM [Quadro K610M]
                vendor: NVIDIA Corporation
                physical id: 0
                bus info: pci@0000:01:00.0
                version: a1
                width: 64 bits
                clock: 33MHz
                capabilities: pm msi pciexpress vga_controller bus_master cap_list rom
                configuration: driver=nouveau latency=0
                               ^^^^^^^^^^^^^^
                resources: irq:37 memory:d1000000-d1ffffff memory:70000000-7fffffff memory:80000000-81ffffff ioport:5000(size=128) memory:c0000-dffff

And I don't see why the kernel would choose to use a different driver
when there are 2 screens enabled.
