Hi Leonardo.

Jung-uk Kim has done a lot of ACPI-related work, so he will probably
know if the change is ok to commit to stable/8.  I've added him to the
thread, so he can let us know what he thinks of the change.  Can you
please post a diff that also shows _where_ the changes have to be
installed in our current version of src/sys/dev/acpica/acpi_pcib_pci.c
for 8.0-RELEASE?
