if iptables works, then nat should be supported.
you should check wether the nat support is enabled in your kernel :
in 2.6.9 kernel, there are 2 options that are needed
Reject target support
did you try a more simple rule, such as :
iptables -t nat -A PREROUTING -j ACCEPT
the rule itself is useless, but this will validate that nat table is working....
