Sounds like a good idea, but in order to do that, we just need to let kernel drivers hook to GPE handlers somehow. I'd be quite happy to add support for it to thinkpad-acpi. I thought your patch did a lot more than this. If I am wrong about it, I apologise. -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
