I have a ricoh webcam inbuilt in my dv6000 laptop. I had an awful time getting it to work , seeing the bad condition of support for Linux. Well,better webcam was a feature for F10 and really got a lot of cameras working. Well, my turn's finally here. Firmware for the webcam has beenpushed into RPMFusion non-free. It hasn't hit the repos yet (I couldn't wait and built myself an RPM).
