Bwired,
I've done some digging in the FHEM documentation to find anything that might help with the MAX! stuff. I'm not sure, but most stuff by eQ-3 nowadays is on the bidcos protocol at a 10KHz datarate. Which is incompatible with the FHT/FS20 system. Some more information can be found here:
http://fhem.de/commandref.html#CUL_HMStill, it's not 100% sure this also accounts for the MAX! system. I hope this helps you a bit. I'll still post a message in the cul-fans (google mailgroup) to see. A search of the group showed there hasn't been any messages on this yet.

I hate to keep posting new messages on my own replies.. so here's an edit.
Been digging a bit deeper, I've found about everything I didn't want to know from instruction manuals in various languages to European conformity documents, EXCEPT for the used protocol. (them fsckers)...
However, making an assumption here, and I'm thinking it's a rather solid one:
Looking at the used device packaging (shape of the product and location of the buttons), it's being used on the 868.35MHz band and the same devices are seemingly also listed in the HomeMatic (bidcos protocol) brochure of 2010... it's fairly save to assume BidCos is being used.
their HomeMatic brochure:
