module fails to load with the following error:
- thinkpad_ec: cannot claim io ports 0x1600-0x161f
A linux-thinkpad developer asked to file a bug in the kernel bugzilla for
someone to check it:
http://mailman.linux-thinkpad.org/pipermail/linux-thinkpad/2008-November/045358.html
Another person hacked the thinkpad_ec driver to ignore the error and it *seems*
to work ok:
