That's an ancient kernel - 9 years ago.  So you're missing the last 9 years
of ACPI fixes.

Also, problems like this are usually caused by the BIOS having buggy ACPI
tables that don't match the actual hardware - and if you're still on 2.6.18,
your BIOS is probably equally out of date.  And you would need to be a *lot*
more specific about the hardware than "x86_64" - for instance,"Dell Latitude
E6530 laptop with BIOS A16".

Unfortunately for you, I doubt anybody is going to want to give much more
assistance than this for free until you're running a kernel from the
last 2-3 years and the most recent BIOS the manufacturer has released.
(I can think of a number of people that will do this for contract work, but
be prepared to pay US$50/hour and up...)
