Ok, I solved the problem: this was a bug of the first NiosII release.

We found it in the "Nios II Development Kit Version 1.01 Release Notes": 

JTAG Identification Conflicts (SPR 157902)
A mechanism was added to ensure unique Joint Test Action Group (JTAG) identifications for each system module in Quartus II projects with multiple SOPC Builder system modules.
