Resources are representing different things on different platforms.

On sparc64 it's actually the full 64-bit physical I/O address on the
system bus being stored in there.  So even IORESOURCE_IO objects have
64-bits of relevancy.

Like I said, printing out the entire thing has helped me find real
bugs, so printing the whole thing is not without merit.
