That's not what I was thinking. Right now, older Thinkpads need polling
if you want to get some keyboard events. However, the BIOS seems to
impleemnt this by calling the ACPI CMOS update methods. Rather than
polling, we can therefore make it event driven. The events won't go out
to userspace, they'll just call a callback in the driver which then
generates input events or uevents or whatever.
