Linux doesn't run on only PC systems though, and other systems use
IRQ0 as the (superio-based) parallel port IRQ.

Indeed - please check the ARM port for our solution to this. We've
had the NO_IRQ construct for literally years in include/asm-arm/irq.h:
#define NO_IRQ ((unsigned int)(-1))
Naturally, a similar NO_DMA is defined in dma.h. The sooner we can get
rid of the "IRQ0 cannot be used" crap from the kernel the better.
