Sorry to jump in late, but isn't the 9.x version of pwc quite old?
IIRC, that is the one that needed a binary blob to work well. It
would work without it, but you needed the binary blob to get full
functionality.
I would be very surprised if that worked on a 2.6 kernel. Have you
tried the 10.0.12 driver (or a later snapshot)? It does not need a
binary blob, works with many more cameras, and is designed for v4l2
in 2.6 kernels:
