Hmmm, could well be, the only problems I'm getting now that can't be solved with some simple configuration options are on the 760's and 765's. (Although by the time the pcmcia driver get to call register_trdev, card_services has allocated the the mmiobase region and shared ram - or *which* may be the problem, it thinks it has.  So ibmtr.c tries to go and use the memory areas and somewhere along the line memory requests don't go to the correct area.  

Sometimes these problems are caused by the tropic chipset having to have mmiobase and shared ram below 1MB, strictly speaking a pcmcia card can put its memory anywhere in the 32 bit address space (just like pci) and some controllers have a tough time mapping below the 1Mb area.

Now, does anybody have 760's or 765's working and with *exactly* what card.
