Just in case this is a real problem I have put together some quick scripts that check for and can remove this. The code is up on github.com as https://github.com/pschlump/linux-rootkit-expunger.git
- rootkit re-adds itself to the /etc/rc.local
- it patches the filesystem functions to hide itself when you read the file, so I am not convined grep will pick it up anyway
- you do not unload the actual kernel module if it is running, nor destroy the rootkit kernel module
- did you test it by installing the rootkit in a vm, and confirm that your code will detect and remove it? if not, i do not think you should publish such code just to give people a false sense of security when they run it and says "rootkit not present"

I suggest you do not claim that your removal tool works until you have tested it successfully. this is true for all software, but is even more critical for something like this, since a false sense of security is actually far worse than just being infected.
if ls -l /etc/rc.local | awk '{print $5}' != \ cat /etc/rc.local | wc -c
Also looks like you might be able to see it running with a ps also.
