What are your idle temperatures with the -RELEASE? If they are still in
60s, I'd say Josh is right and -RELEASE is just masking hardware problem
better than -STABLE. If they are down to more reasonable 40s, I would
look some more into the software -- taking apart X60 will be harder than
taking apart T60 or R60 -- there are pieces of the casing that break off
easily enough even during the normal use. Like the molding around the
infrared sensor on the front right.

Just my 2c.
