I'm having a problem with the sg module on ubuntu netbook. Here's what it says:

me@ubuntu:~$ modprobe sg
FATAL: Module sg not found.
The readme for the program I'm trying to use says to modprobe sg and then install libsgutils2-dev.
I have a suspicion that it has to do with the fact I'm using ubuntu netbook... It works on my other computer that has the desktop edition.
