IRQ passing uses the vm86() calls listed under "IRQ Management" here: http://naesten.dyndns.org:8080/vm86.html Those are not available on x86-64. As this page says, this "facility actually has little to do with VM86 mode". Perhaps there are other system calls that allow you to pass on IRQs in Linux but I'm not aware of those.
