I know you're re-working this thing by now, but still: Can we be certain that BIOS, ACPI etc. properly report all io resources which must not be utilized by other devices? Does this really depend on ISA being set in Kconfig? Should this also be enabled for CardBus bridges on the root PCI bus? And: could doing a check for X86 like in rsrc_nonstatic.c ( avoid anything < 0x100 for ioports ) help to avoid some of the possible fallout?
