In a native case, as you said, only 16 or fewer (if legacy ISA card
exists) PCI-e slots can be assigned with I/O resources. Say an
admin wants to insert a bootable card. How can this guy know 
which slot will be granted with I/O resources by kernel? Does 
native Linux provide similar cmdline as your approach to assign
which slot to be I/O capable? Or admin has to use lspci with
assumption that next boot kernel will assign I/O in same way?

Not relevant to your patch here. Just interested about how this
big box works on native.

Thanks,
Kevin
