Hi,

I have updated my ACPI CA(acpica-unix-20021205.tar.gz) code,
and it works fine for me.
 
I have put that patch at:
    http://www.ann.hi-ho.ne.jp/~kanaoka/acpica-20021205.diff.gz

	% /usr/bin/md5 acpica-20021205.diff.gz
	MD5 (acpica-20021205.diff.gz) = 6b4f70b64326bef27bde63221ec50b6e

You can try it like below:

 	# cd /usr/src
 	# zcat /somewhere/acpica-20021205.diff.gz | patch -p1 -E
	# cd /sys/arch/i386/conf
 	# config your-config;cd ../compile/your-config
	# make depend;make;make install

You can find chang log for ACPI CA code at:

If you are interested in it,How about trying it?
Regards!
