Okay, I made another change. I got this from the boot-up messages:

Mar 14 15:16:44 scorpio1 kernel: siba_bwn0: <Broadcom BCM4318 802.11b/g Wireless> mem 0xfdefe000-0xfdefffff irq 16 at device 1.0 on pci2
Mar 14 15:16:44 scorpio1 kernel: bwn0 on siba_bwn0
Mar 14 15:16:44 scorpio1 kernel: bwn0: WLAN (chipid 0x4318 rev 9) PHY (analog 3 type 2 rev 7) RADIO (manuf 0x17f ver 0x2050 rev 8)
Mar 14 15:16:44 scorpio1 kernel: bwn0: DMA (32 bits)

So, I made the following changes to the rc.conf file:

## Wireless
siba_bwn0="wlan0"
ifconfig_wlan0="WPA SYNCDHCP"

Now the system does not hang, but it doesn't bring up the wireless
network either. This is the output from "service netif restart"
