Hi Dave,

This will only work for new Optimus laptops, not the older ones such as your 
Lenovo T410s or on a Dell Vostro 3500 with a GT 310M. Is that intended? If 
not, check for those models too:

	return nouveau_dsm_priv.optimus_detected || 
          nouveau_dsm_priv.dsm_detected;

Regards,
Peter
