Router take advantage of device polling

[Jeffrey Lyon]

I am currently running a router pushing about 15 megabit of traffic, 
with CPU usage like so:

root     25  5.9  0.0     0   12  ??  WL   10:16AM  47:49.70  (irq7: 
bge0 amr0)
root     14  5.9  0.0     0   12  ??  WL   10:16AM  55:15.63  (swi1: net)
root     26  3.0  0.0     0   12  ??  LL   10:16AM  28:42.81  (irq5: bge1)

I am told that activating the device_polling kernel option will cause a 
substantial reduction in this usage. Is there any truth to that statement?

Thanks.
