I've got a QNAP TS-209 II running lenny and I wanted to install SqueezeCenter 7.2.1.

Got debian installed using this http://www.cyrius.com/debian/orion/qnap/ts-209/

Code:
john@georgia:~$ uname -a
Linux georgia 2.6.26-1-orion5x #1 Fri Oct 10 12:35:08 UTC 2008 armv5tel GNU/Linux
john@georgia:~$ cat /etc/debian_version 
lenny/sid
john@georgia:~$ dpkg --print-architecture
armel
I added the debian feed to the file /etc/apt/sources.list, but...
Code:
john@georgia:~$ sudo apt-get update

I've looked around here I the forum, but haven't found anything appropriate.
Now I'm hoping someone can help me wrap up a debian package for this device. Can someone give me a few pointers?
