Where do you get tun.ko from? Why isn't it included in openvpn-installer?

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install openvpn-installer.

What is the expected output? What do you see instead?
I expect to install openvpn and tun.ko because both are required. Without 
tun.ko, I get the error message:  fatal:  cannot allocat tun/tap device 
automatically

What version of the product are you using? On what operating system?
Latest version of openvpn-installer from android market 5/3/2011: Openvpn 
2.1.1, openvpn installer 0.2.3.  And I'm on android 2.2

Where should I find the download for tun.ko?
