Fighting against my Fritz Card DSL SL

So today i tried to get my Fritz Card DSL SL to run...
After 3 hours of hard work I'm at a point where I found no solution to my problem. The tool "drdsl" exits with a segmentation fault before spitting out the right VCC options. I found two other people having the same problem, but they had no solution either... :-(
Perhaps i simply have to upgrade the kernel...
