Well, what Apple does in Darwin is to trigger a timer after a keypress or release (that is a keyboard action) and to ignore a tapping state change of the trackpad until this timer expires (typically a few milliseconds). This avoids spurrious trackpad taps on those new over-sized trackpads when typing on the keyboard. It could be easily put in the kernel, but not before we have a way to simply configure and turn it on/off, along with other trackpad features, via the yet-not-written /proc/bus/adb interface ;) Ben.
