However, request_irq() is called with IRQF_SHARED only, so neither
IRQT_RISING nor IRQT_FALLING is set and the value defaults to
IRQT_NOEDGE. How can you get IRQs?

Actually, the best way to go is to let the platform resources flags
decide about that with something like
resource->flags = IORESOURCE_IRQ | IRQT_RISING;
but the dm9000 does not care about them at all. Changing that would also
imply modifications to all board support code.
