I do this under DOS for a battery of human performance tests. However, it requires taking over the system clock _and_ the keyboard interrupt to time keypresses to the nearest millisecond (and you can get a bit more than that if you want). If anyone knows about how to do this under Linux, I would love to port these tests over.
