Have you guys been able to try this on FreeBSD 8.0-Release as well? The 
8.0-Alphas we're based on FreeBSD 8.0-PreRelease, and its possible 
something got broken when we moved to 8.0-Release :(

Also, you may want to post some of your findings over to the ACPI list:


Some of the devs who hangout there may be interested in these errors, 
and maybe have a solution :)
