Sorry to disappoint all the people waiting for the Linux UVC driver, but the 
code won't be ready in time for 2.6.21. There are still two matters to be 
addressed:

- adding the necessary controls to V4L2
- adding support for vendor-specific extension units

The first step is the most difficult one, but I still hope to convince the 
V4L2 developers :-)

In the meantime, the driver can be found on http://linux-uvc.berlios.de.

Best regards,
