Hi,
 
My source files under sys/dev/acpi/acpica/Subsystem were caught up
with acpica-unix-20030321.tar.gz, and it works fine for me.

This patch include for sys/dev/ac@i/acpi_ec.c.
I don't have acpi ec device,so I don't test it.
  
 I have put that patch at:
     http://www.ann.hi-ho.ne.jp/~kanaoka/acpica-20030321b.diff.gz

	% /usr/bin/md5 acpica-20030321b.diff.gz
	MD5 (acpica-20030321b.diff.gz) = 2396234d3dea03f106d01def196ad0d6

You can try it like below:
 
  	# cd /usr/src
  	# zcat /somewhere/acpica-20030321b.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 release note for latest ACPI CA(20030321) code at:
    http://sourceforge.net/project/shownotes.php?release_id=14974

I don't know why intel web site does not update.
 

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