I decided to install OpenSuse 10.3 in dual boot with Vista on my laptop, Sony Vaio SZ4MN. Everything it seems to work very well, without any problems, but I still have to test the modem and suspend to ram/disk.
After I did a kernel update from 18.104.22.168-31 to 22.214.171.124-0.1 and I realized that my webcam didn't work. It is a Ricoh WebCam. I found that I have to reinstall the driver (the following packages: r5u870-default and r5u870-firmware), but before, I removed uvcvideo-default and gspcav-default packages.
After installing also jasper (Kopete needs it for webcam support) everything is fine again.
Note: If you have one of the following VAIO models: AR11, FE, AR21, SZ, UX, CR, FZ, or any HP Pavilion machine with a built-in webcam, you should also install this driver.
