Sierra Wireless MC8775

Hi.
I’m a new Linux user. So, I don’t have much knowledge about Linux. But hej, anything is better than Windows. I bought a new laptop, a LG R405, it has a micro card for UMTS/3G from Sierra Wireless. It works fine with openSuSE 11 Gnome but I like KDE version. Unfortunately I couldn’t make it work with KDE. I tried to find a solution to make it work but unfortunately there wasn’t one. Does anyone know how to make the Sierra Wireless MC8775 work with KDE? Thank you for all help.
Best regards
