I have no idea what the relative power consumption is for USB and PCI.
Certainly, a PCI card can assume a cleaner power source - the USB is
going to have to do heavier regulation.

One other thing to try is to turn off the LED. Unset
CONFIG_MAC80211_LEDS in your .config. That should save some power.
