For what it's worth, I never got my logitech quickcam notebook pro working _without_ pwcx. With it it is working fine. (except that I have to unplug it and plug it in again if pdp closed it/crashed. Otherwise I get a blackout every second or so. With Gem it just works.
I am using the 0.9 beta drivers.

Yep. That did the trick. The image was very garbled and it ate up ~30% of my processor cycles, but it worked. I'm still going to try kernel compilation and pcwx, but I don't think that will fix it.
