Well... the problem happpens in console as well, and with other
non-X apps like MacOnLinux. Some Apple PowerBooks have
over-sensitive trackpad. Apple themselves implement a similar
mecanism in the kernel driver of OS X.

  Mine is one of those machines.  I have to turn off gpm for sure,
and X is quite oversensitive too (tuned it in KDE, but still this
functionality would be very nice).

How about implementing it in mousedev.c?

Right, though it would need hooks in kbddev or something to know
about keystrokes.

It could accept keyboards as an event source for this purpose. I'd like
to keep this out of the input core.

Hmm, this reminds me of one feature I would need in the input core to support
1-button mices in userspace (or at least in a totally self-contained module),
namely the ability to register "filters" that are called early in
input_event() and where a return value !=0 lets it return immediately from
input_event() without processing the event.

Eg. something along these lines:

	ret = 0;
        list_for_each_entry(filter, &dev->f_list, d_node)
                if (filter->open)
                        ret |= filter->handler->event(handle, type, code,
value);
	if (ret) return;

Comments?
