Except the memory issue only popped up when I started hostapd. When I 
ran the same system as a station and wpa_supplicant, there were no 
memory issues - just connectivity issues between wpa_supplicant and  
hostapd.

Another issue that may be indicative of a non-hostapd issue is the flash 
drive I'm using may be getting flakey as well (crc errors on loading the 
kernel from a warm boot, for one).

At any rate, I updated the madwifi driver to the latest revision (r3065) 
and it appears to have fixed the memory and connectivity problem - still 
looking at some connectivity issues, but I'm still checking on that.
