I don't have a webcam myself, but I saw that Logitech webcams work well with Pardus.
qc-usb and
qc-usb messenger are the drivers you need:
The qc-usb driver is known to work with the following webcams:
* Dexxa Webcam
* Labtec Webcam (old model)
* LegoCam
* Logitech QuickCam Express (old model)
* Logitech QuickCam Notebook (some models)
* Logitech QuickCam Web
