I haven't tested WRT54GS, but WRT54G seems to be working fine with
wpa_supplicant. I would assume WRT54GS is quite close to WRT54G as far
as software on level concerning WPA authentication is concerned.
What firmware version are you using in the WRT54GS?

That is likely to mean that the authenticator did not like something in
the EAPOL-Key packet from the supplicant. If you get to msg 2/4, the
association seemed to have succeeded and at least the client is able to
receive EAPOL-Key frames from the authenticator.

I would like to see full debug log from wpa_supplicant (-dd on command
line and leave it on foreground). In addition, it would be useful to get
a sniffer log of the negatiation. Ideally, this would be from a wireless
sniffer (included IEEE 802.11 headers and all management frames in
addition to EAPOL-Key data frames); however, even a sniffer log from the
client host (e.g., tcpdump/ethereal dump from the wireless interface)
would be useful.
Debug log from the authenticator would of course be useful, but I don't
know whether that would be easily available from WRT54GS.
