Cheese with corrupted webcam image

Under nouveau, the image from my webcam gets corrupted when I view it in Cheese
or Skype - the top 5% is shown correctly, but the rest is solid green (see
screenshot).

When running Cheese, I get lots of errors like "libv4lconvert: Error
decompressing JPEG: fill_nbits error: need 6 more bits", but no errors from the
kernel.

The webcam works fine when I use the blob. My card is an 8400M GS.

Apparently this was caused by some acpi boot options I had added, or possibly
the backtrace seen at the end of the X log.

Anyway, this works now so this bug can be closed. Sorry for the noise.
