What media options have you set? In adhoc mode, wi either provides
the quality/signal/noise for some arbitrary station, or else it punts,
which is generally useless and misleading. (Ditto hostap mode, but you
are not using that with Lucent.)

Does the firmware version on your cards vary a lot? Possibly early
firmware did not provide the quality/signal/noise indication.

I have estimated that wi can take 15%-20% CPU; is that about what you
see? For lower CPU usage, try atw or ath.
