I did some more digging tonite and think I found out how I'm getting
stuck in 802.11a mode.  The madwifi driver supports the following values
for the 'mode' parameter:

iwpriv ath0 mode 1              lock operation to 11a only
iwpriv ath0 mode 2              lock operation to 11b only
iwpriv ath0 mode 3              lock operation to 11g only
iwpriv ath0 mode 0              autoselect from 11a/b/g (default)

If I'm reading the NM code correctly, nm_device_new calls
nm_device_set_mode(dev, NETWORK_MODE_INFRA) where NETWORK_MODE_INFRA is
the numeric value 1.  This locks the atheros card into 802.11a mode,
preventing it from associating with my Linksys WRT54G.
