it was a SN2318 led-controller. to be sure it's not a dead chip i just connected an LM75 temperature sensor, which is a relatively simple chip. same as before (it should show up on address 7):

70: -- -- -- -- -- -- -- -- I have read that on the raspberry pi it is neccessary to load i2c-dev (which should be active here, otherwise i would not see the /dev/i2c-files, right?) and a second kernel module, that allows to access the processors i2c-bus (usually called i2c_bcm8xxx).
Is this module maybe missing? Or is it included in the 8723bs or the vfe-io?
It seems strange that the buses show up, but not their connected devices.
