Getting the output from your _STA methods matched to each Device object
would be good.  Stick a printf at the end of acpi_DeviceIsPresent() using
AcpiNsHandleToPathname() (see acpi_UserNotify for an example) and also
print out the _STA value.  Then we'll know which objects return which _STA
values.
