The config I used for the Soekris 4521 was identical to
http://www.ultradesic.com/pub/FreeBSD-6.2_Files/NET4521
with the addition of the wi and ath modules

device ath # Atheros cardbus/PCI NIC's 
device ath_hal # Atheros HAL Hardware Acces Layer 
device ath_rate_sample # SampleRate tx rate control for ath 


Why this solved the problem beats me, but the system has been running
stable now with the CM9 card (AR5212) for several days and also (on a
different system) I see no error messages with the WML54AGP23 (AR5414)
card.
