Anriy, it is _before_ setting it. I just disabled it and checked again to make sure. With the option set, the result is the same it seems, unless I ovelooked some little digit.

I attached you my acpidump result.

I'll see about the report after I rebuild the base system again.
Thank you man!

Attilio, if you ask me about the CVS version of the source, I'm afraid I don't know where to take that from. But here's my `uname -a` result, there's the build date where you can find out the version, please tell me if there's something else to help:

FreeBSD free.bsd369441.org 8.0-STABLE FreeBSD 8.0-STABLE #0: Tue Apr  6 01:10:20 EEST 2010     root at free.bsd369441.org:/usr/obj/usr/src/sys/GENERIC  amd64

I will recompile the kernel these days and come back to you.

Thanks a lot!
