No you shouldn't. The i440fx should merge and arbitrate the mappings
and then push *direct* links to the handling functions at the top
level. Mapping changes don't happen often on modern hardware, and
decoding is expensive. Incidentally, you can have special handling
functions which are in reality references to kernel handlers,
shortcutting userspace entirely for critical ports/mmio ranges.
OG.
