Ok. I've fired off an email to some Intel people asking what the
real rules are wrt Intel PCI-PCI bridges. It may be that it's not that
particular chip, but some generic rule (like "all Intel bridges act like
they are subtractive decode _except_ if they actually have the IO
start/stop ranges set" or something like that).
If anybody on the list can figure the Intel bridge decoding rules out,
please holler..
