Probably not, because with the very same hardware on Maverick (kernel 2.6.35-29-generic) powertop counts only 35 interrupts/sec with wireless disabled and about 85 with wireless enabled. Estimated power consumption is 6,6 vs 6,5 W.

On Natty (amd64) with Nvidia binary blob, running on Asus M4N68T motherboard with AMD Athlon II X2 240e CPU, powertop reports about 185 interrupts per second when idle. Disabling remote control polling in dvb-usb module brings this value down to 35 interrupts/sec.

It means, without a carefully defined and unified hardware and software configuration, bare figures are meaningless.
