Hi,
 
My source files under sys/dev/acpi were caught up with 
acpica-unix-20030523.tar.gz. I tested kernel with this patch 
several hours and it works fine for me.
  
   I have put that patch at:
       http://www.ann.hi-ho.ne.jp/~kanaoka/acpica-20030523.diff.gz

       % /usr/bin/md5 acpica-20030523.diff.gz
       MD5 (acpica-20030523.diff.gz) = 9a1c5045377480274d6a08c722945483
 
You can find changes for latest ACPI CA(20030523) at:
     http://developer.intel.com/technology/IAPC/acpi/downloads/CHANGES.txt

Any comments?
Best Regards
