I downloaded the file and have tried to install it (I ran the first command you gave me), but it gives me an error that I'm running an X server and that I need to log out. What's an X server and how do I log out of it?
: Scratch the above. I googled it. Now the problem is that it can't find the kernel sources. They don't seem to be at the default location even though I installed them with YaST.
: Alright, figured it out and it all works. After I installed the kernel sources from the install CD, I had to go back to the online update, and updated the kernel source. After that, it worked just fine. For anybody reading this who's in the same position I was in, to shut down the X server, hit CTRL-ALT-F1. This will take you to a terminal screen. After that, log in as root, then type "init 3" (without the quotes). That will shut down the X server. Now run your commands. In order to bring the X server back up again when you're done, type "init 5".
