The problem and solution is already written down in the forums over a billion time now, but i write it down for the last time:

Problem: fcam-drivers and power-kernel conflicts with each other.

Solution 1) remove power-kernel or fcam-drivers and use only one from the both
Solution 2) set up a multiboot system to boot from stock kernel to use fcam based applications or to boot up from power-kernel
Solution 3) install power-kernel-maemo37 (an older version) witch still works perfectly with fcam-driver
