OK, you got me there, this is a terrible coincidence

any idea where I could head now to get this SD slot to work? I 
understand this topic has been visited before and there's some 
documentation from Ricoh (which I haven't seen/read) lying around

I could buy a multicard reader PCMCIA card, but I refuse to do so since 
the laptop already got an SD slot that should work

thanks a lot for your time Russell :)
