I still wait for the delivery of my RPi2. Then I'll be able to figure out if there's any difference to the first RPi. For my setup I've applied the pin settings shown in this documentation: http://geraintw.blogspot.de/2014/01/rfid-and-raspberry-pi.html

Probably it will be that:

"On RPI 2, the peripheral addresses are different and the bcm2835 library gets them from reading /proc/device-tree/soc/ranges. This is only availble with recent versions of the kernel on RPI 2."
