I am facing a similar situation: attempting to set up a
webcam under sid. Not succeeding in getting any display yet.

2.6.26 doesn't have gspca, but 2.6.29 does.
 
I've tried 

- two webcams
- amd64 and 486 kernels
- camorama and skype

Both cameras are recognized, creating /dev/video0.

$ lsusb

Skype lists no video devices with either camera, either
kernel.

Here is the output of camorama, which defaults to /dev/video0

$  sudo camorama -D

Any suggestions on troubleshooting/testing?
