 Unfortunately, it does not work (nor using 0xEB instead of
 KBC_SETDEFAULT).  Touchpad still not working (that, I don't
 really care as I don't use it) but touching it for the first time
 still hangs the keyborad (that, I use a lot).

 Using KBC_SETDEFAULT need #include <dev/pckbport/pckbdreg.h>
 somewhere.  Anyway, it's not working.
