Well, I am a little bit worried that /dev/video* entries will renumber themself when the the front camera support is merged, breaking userspace.

Could it be that the ISP > clock is lower than it should be for some reason, for instance? No idea, really. I'd like to get the support merged, and then debug the code when we have common code base in the mainline.
