There is a bug here in that acpiphp shouldn't even be used on the X60 - it has no hotpluggable slots. This problem only occurs when acpiphp is built in, as when a module it just doesn't load. It appears to not clean up after itself properly when it finds no ejectable slots and leaves the acpi notifier installed for the PCI Root Bridge. The message is printing "cannot get bridge info" because it partially cleaned some stuff up (without actually removing the notifier). I'll put this bug into bugzilla since I won't have time to fix right away: http://bugzilla.kernel.org/show_bug.cgi?id=7452 Feel free to add yourself to the CC list if you are interested in being notified when it is fixed.
