I am *really* excited to hear this.

Since you JUST got this working (including patching) could you share a 
step-by-step on how to get this included, working etc.

Something like:
    Install Fedora 12
    yum install kernel-devel kernel-headers ....

My challenge is I recently moved from Debian/Ubuntu to Fedora and Fedora 
does things differently
    (I patched /usr/src/linux/ in the past... not the Fedora way)

If someone wants to share lots of stuff, I am happy to test and write it 
up, but I can see wasting lots of time trying to get this to work. So 
any pointers, lessons learned, etc is welcome. Even, hey stupid, read 
this URL and then patch (from here) and load the module....
