 Using 36-bit pointers for PCMCIA seems questionable to me -- does the bus
support such wide addresses?  If not, why not use a data type that covers
valid offsets only when passing addresses to bus access functions?  In
particular, the range of offsets (the data type used) shouldn't depend on
the processor type, should it?
