Just out of curiosity, are you sure it's not the REJECT which causes the
invalid argument ?

could you try :
 - iptables -t nat -A PREROUTING -m physdev --physdev-in eth0 -j DROP
 - iptables -t nat -A PREROUTING -j REJECT

and check which one returns an error ?

Was your iptables-1.2.9rc1 compiled with 2.6.0test8 headers or with 2.4
headers ? it might make a difference.
