[Madwifi-users] oops in ath_init

[<nc...@ko...>]

Using madwifi from CVS a few days ago. Noticed that ifplugd was the culprit, 
and since I don't need it for ath0, removed ifplugd, and now ath_pci loads 
fine. The ibm a/b/g card works an order of magnitude better than the dlink I 
had, not a single drop from the AP so far.
