Getting it fixed properly depends a bit on the PCI implementation.
I've been planning to clean up this part of the ARM architecture
for some time and I can probably do it for one more platform when
I get to it.
My idea for the multiplatform kernel is to have a global I/O space
window (maybe 1 MB) that is in the same location in the virtual
address space all the time, so any platform that wants to support
PCI with direct-mapped I/O space can simply map it in there
at boot time.
