Santa Rosa 661-4576 compatibility with Penryn 661-4709

I've got a faulty logic board (part number: 661-4576) on my MacBook 13" Black 2.2 GHz (Santa Rosa).

instead of just replacing it I'd like to take this opportunity and upgrade to a 2.4GHz, but the only ones available are Penryn (part number: 661-4709). is that possible?

both look very similar, as well as their specs, but I am not 100% certain of their inter-compatibility.
