Please cc acpi-jp list with acpi problems, as I have on this reply.  Check
the current@ archives for the patch 20021122 that iwasaki@ posted.  It may
fix your problem.  However, this sounds similar to another user's problem
where his dsdt didn't forward declare FAN_ (again, check archives for the
past 2 weeks).
