Did you play with nvidia-settings? Maybe also wipe out xorg.conf and start afresh.
Thanks for all your suggestions. I spent a few hours fiddling with various driver versions and configurations. In the end, I simply ripped out the %&#@$ Quadro card and replaced it with a GeForce 8300, which works perfectly with the kmod-nvidia-340xx driver.
Cheers,
