Hi,

I commited small changes to make the ACPI CA a bit permissive:

   * give up trying to check status for unresponding hardware
     when entering sleep state
   * emulate ReturnOp where expected, but not existing
     for some buggy firmwares
   * allow out-of-boundary access to regions for some
     buggy firmwares

These changes are from FreeBSD's local changes. They do not
affect normal users whose ACPI is already working well.

If you prefer the original strict behavior of ACPI CA,
you can disable these by adding 'options ACPICA_PEDANTIC'
to your kernel config file.
