I should mention that the problems occur under Linux 2.4.? (? < 10)
and that the hat switch works ok under Windows though I don't know the
mapping there as it is hidden.  So I think that the explanation
from David Megginson (bug in the kernel joystick code) sounds logical
though I never would have thought of that.
