Considering that handle_keypress() invokes non-IRQ-handler functions directly
only when !in_irq(), I can't help getting the impression that in_irq() returns 
the
wrong value here. This, however, would then not be a new problem, as nothing
here really changed recently (the only recent change got reverted), or at least
I'm unaware of any change which might have affected this.
