Arg, what I meant to write was "seem to *never* raise several interrupts".

lubbock_irq_handler() is never called.
pxa_gpio_demux_handler() is never called.
  => this is the one worrying me most.

And as the lubbock_irq_handler() is never called there is not point in printing
that yet, first should be finding out why on earth the gpio demux is not getting
called.
