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.
