Yes. My another machine's interrupts are as follows:

[root@localhost ~]# cat /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 23
model name      : Pentium(R) Dual-Core  CPU      E6700  @ 3.20GHz
...
[root@localhost ~]# echo 3 > /proc/irq/18/smp_affinity
[root@localhost ~]# cat /proc/irq/18/smp_affinity
3
[root@localhost ~]# cat /proc/interrupts | grep eth2
  18:        455       458   IO-APIC-fasteoi   eth2
[root@localhost ~]# cat /proc/interrupts | grep eth2
  18:        463       467   IO-APIC-fasteoi   eth2
[root@localhost ~]# cat /proc/interrupts | grep eth2
  18:        471       476   IO-APIC-fasteoi   eth2
