Absolutely not. The rotten IRQ thing gives you the old irq.c which assumes
more or less x86 centric interrupt handling, that is a 2 PICs and doesn't
get SMP right and leaves us a ton of structural problems. Don't use, it's
destilled evil ;-)

Interrupt handling is an per architecture thing; currently i386 is coming
closest to the new design of our future interrupts.
