I've added code that should turn this error into a warning. Please test.

Raymond Tay had tracked this down a while ago, quote:

It slipped my earlier observations that whenever i ran the SDK
deviceQueryDrv, the clock rate was always displaying as "0.0 Ghz" and it
didn't occur to me that my Mac Book Pro (has 2 GeForce cards - 9400m and
9600m) was choosing the 9400m low powered chip and for some reason the 9400m
device wasn't returning properly but i dont know enough to know why this is
occurring

Is this a bug with nvidia or with mac os x? I don't know
