Radeon 9600 PRO PC & Mac Edition - compatible?

Does Anyone know if the new Radeon 9600 PRO PC & Mac Edition card compatible with Motion?

I assume it would be, however I haven't seen it on any lists as a compatible card. I was looking to upgrade my G4 to be motion compatible, and since it's a 256 Meg card rather then 128 I'd rather do that then put in the 128 Meg Radeon 9600. But wanted to make sure it would work.

Thanks for any input.
