Greg Troxel helped me to find out, that this issues was caused by the  
fact, that rtadvd was handing out addresses with a prefix length of  
48. Once I (correctly) set the prefix length to 64, things worked as  
expected.

I don't know if things are supposed to work that way, or if it is a  
bug. If not, some clarification on this in the documentation would be  
great.
