When I do a lsmod in 2.6.18 it comes back as an underscore.  Did this change in
2.6.20?

Here is the output of uname -a and lsmod

Linux tupari.net 2.6.18-1.2868.fc6 #1 SMP Fri Dec 15 17:32:54 EST 2006 i686

The kernel converts "-" to "_" during loading for some reason.

Go compare those names and you'll see.
