Almost exactly the same here!
Difference is that I've got an Ambient / Intel HaM V90 modem...suspect it's a pretty similar beast.
YaST seems perfectly happy with it, and it does seem to dial out...I can then hear a short stream of data being sent, and then the modem clicks off...and dials again...and repeat...
This happens when using both kinternet and kppp. As a complete newbie (I only installed SuSE two days ago!), I have no idea what cinternet is.
