It is related to the fact that the pci bridge really passes all
addresses back upstream, rather than the addresses listed in the pci
bridge registers. newer versions handle this correctly, completely
eliminating the allow_unsupported_io_ranage option. You should try a
number higher than 0x20000000 since that's kind of low...
