Iptables problem with ipset

[joximus]

I'm trying to block connections from china to my cubieboard using ipset. I have created set with
$this->bbcode_second_pass_code('', 'ipset -N china hash:net.')
ipset list shows:
$this->bbcode_second_pass_code('', '
Name: china
Type: hash:net
Revision: 2
Header: family inet hashsize 1024 maxelem 65536
Size in memory: 8508
')
However when i try to add iptables rule:
$this->bbcode_second_pass_code('', 'iptables -A INPUT -m set --match-set china src -j DROP')
I get following error:
iptables: No chain/target/match by that name.

lsmod shows modules :
$this->bbcode_second_pass_code('', 'Module Size Used by

Can anyone help?

I have noticed that this work without problems on my x86 machine running Arch.
Maybe the problem is that module xt_set which is loaded on x86 does not exist on my cubieboard?
$this->bbcode_second_pass_code('', 'modprobe xtset
modprobe: FATAL: Module xtset not found.
')
Can I expect that module will be built on some future versions of linux kernel?
