I don't see any message that something is found, nor can I definitely say 
where an error happens. I mainly see two parts: one where cardservices are 
initialised and one where the driver registers itself. The former doesn't say 
it found anything at all, maybe that is already the problem... I'll 
investigate further.

Could you post the relevant messages of a working system, so I could compare 
that?

Hmmm, I just had a scary thought: I don't have any userspace programs running 
yet, meaning also no cardmgr, because I intend to boot from that CF card - is 
that possible at all? FYI, I don't need any hotplugging at all.

thanks
