>Description:
re-installed current, tested sysctl -w machdep.sleep_state=3 

machine suspends to RAM fine

on restore, ath0 is re-enabled via /etc/rc.d/network start but there is no 
DHCP. I checked via tcpdump -ni ath0, and wlanctl -a and ifconfig but it does 
not see any attachment at the network/link layer. 

I have 128bit WEP, I also tested flushing WEP keystate and restoring.

when I flush web, I get syslog of:

ath0: deleting keyix <n> w/o power

platform is IBM X31 laptop
