setrunqueue() would fix it up for us in the non threaded case. The

the driver has unholy private knowledge of its great-*cgrandchildren.
The ACPI allocation routine lacked such knowledge when it tried to do
a default allocation for all descendants, rather than just its
immeidate children, so would access grandchild's ivar in an unsafe
way. This could lead to a panic when devices were present which had
no addresses setup by the BIOS, but which were later allocated in a
lazy manner via pci_alloc_map. As such, only do the default
allocation adjustments for immediate children. The manner that
acpi_sysres_find accesses the resource list, used later in
acpi_alloc_resource, is safe and proper so no additional test is
needed there.
This fixes a panic when probing an disabled ata controller on some
newer intel blades.

make sure that we restore the value to the BAR that was there before
if the bar is 0. Chances are that it was 0 before the write too and
that the restoration is a nop, but better safe than sorry.
