I think we really need them by default. I had seven bugs with touchpads, lost synchronization with PS/2 mice and similar fixed just by enabling this patch unconditionally in the SuSE tree.
As far as I know, there are only a few nForce boards where enabling the patch hurts - we should be able to do a DMI exception for those. Anyway, those boards have bigger problems, as USB reportedly doesn't work there (because the USB drivers do the same handoff).
