I've been thinking about changing that to normal ioremap's like ppc32,
relying on normal pointer arithmetic to get us the right address, but
that would only work if all drivers properly stored their IO port "base"
in a long, not an int, which might not be the case...
As I wrote earlier, I also want to get rid of the imalloc stuff ....
Ben.
