berryboot的ubuntu怎么编译内核？

cubielinaro

my cubieboard have a etho and a wlan0
install  Linaro_Ubuntu_ALIP_2012.11.img with berryboot
I plan to set up NAT service in it.
this is my config for NIC:

root@linaro-alip:~# ifconfig
eth0 Link encap:Ethernet HWaddr 66:cf:91:51:86:9d

inet addr:192.168.100.1 Bcast:192.168.100.255 Mask:255.255.255.0
UP BROADCAST MULTICAST MTU:1500 Metric:1

lo Link encapocal Loopback

wlan0 Link encap:Ethernet HWaddr 48:02:2a:67:38:dd

inet addr:192.168.0.20 Bcast:192.168.0.255 Mask:255.255.255.0

collisions:0 txqueuelen:1000
RX bytes:32938 (32.9 KB) TX bytes:16682 (16.6 KB)

and I also modified the /proc/sys/net/ipv4/ip_forward

when i set up the iptables,i got a error message
root@linaro-alip:~# iptables -P INPUT ACCEPT
root@linaro-alip:~# iptables -P FORWARD ACCEPT
root@linaro-alip:~# iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
iptables v1.4.12: can't initialize iptables table `nat': No chain/target/match by that name
Perhaps iptables or your kernel needs to be upgraded.

then I try to load the modules:
root@linaro-alip:~# modprobe ip_tables
root@linaro-alip:~# modprobe ip_conntrack
FATAL: Module ip_conntrack not found.
root@linaro-alip:~# modprobe iptable_filter
root@linaro-alip:~# modprobe ipt_state
FATAL: Module ipt_state not found.

so,I need to recompile the kernel with these modules

question is How to recompile the kernel?
