My PCMCIA controller is a VG-469, handled by i82365.c.  Its memory
space is at physical address 0x10000000-0x10FFFFFF.  By "address less
than 16mb" I meant from i82365.c's point of view; it's passing that to
ioremap and needs read[bwl] and write[bwl] to work on the result.
When ioremap adds 0x10000000, things are (mostly) happy, but is that
the wrong way to do it?

That fixed those problems.
