What about the formatting and field widths ?

ulong would probably be a lot saner than kio_addr_t and yet more type
obfuscation.

I don't think anyone uses ioports > 32bit.  Certainly i386 takes an int
port as parameter to {in,out}[bwl] (and it really only uses 16-bits).
parisc uses 24 bits.  I don't know what the various ppcs do, but pci
bars can only be 32-bit for ioports.  So my opinion is that ioports
should be uint, not ulong.

The kernel seems to mostly use int, sometimes uint.  I never quite got
why pcmcia had to have it's own strange typedef for them.
