Legacy X, and non-BAR X memory (originally ISA, of course; now
probably more often "stolen system memory").
For legacy memory, we actually have /sys/bus/pci/<busno>/legacy_mem
(though ia64 may be the only supported platform). It's actually
required on some arches due to the way this space is allocated across
the system.
Well, it's certainly not under /sys/bus/pci on x86 systems...
