405GP i2c slave handling

I am trying to get i2c slave behaviour to work (currently only
writes to our device) but run into some problems:
When reading/writing with two of our boards everything works
fine, but when working with the device I actually want to address
(an IPMI BMC on an Intel SDS2 Board) the first bytes are received
correctly, but after this the BMC sends the message again and (the
most strange one) before this I get my own address byte in the
slave receive buffer, which absolutely should not happen.
So I guess our device behaves wrong in some way while
receiving/acknowledging the bytes. I am using the 405 IIC
interface, not the direct control of clock/data.
Did anyone work with i2c as slave and/or has some hints for me?
