I meant messages indicating that the nvidia binary-only driver has been loaded, like the one I've left unsnipped above. (There are others, but that's the clearest one.)

[1] has a rough overview of the current state of nouveau power management --- NV40 looks like it has ok support, and your card advertises only one performance level, but probably there is still something that could be done.

Right. We should probably take this upstream soon, so if you get a chance to try with the virtualbox and nvidia drivers blacklisted, that would be useful. Thanks again for the quick feedback.
