LXDE repo for ARM Devices

[rohan]

Hey guys,
I'm currently working on a Ubuntu chroot port for the HP Touchpad and have been greeted with some success. One thing though:
I successfully am at the chroot. It is the natty version of it. The HP Touchpad has a ARMv7 processor. I need to get the correct repo to add to the sources so that lxde can be installed as a GUI so that new users aren't turned away from the port.
So I need to know the armel repo for LXDE (specifically one that is geared towards natty).
Thanks in advance.
