I tried using the ko files from your directory, but I received a
Invalid Symbol message.

i running two separate clusters with the following packages.  Can you
create a ko files that will work in these environments to test?

Envirorment One  x86_64
uname -r = 2.6.9-42.0.3.ELsmp

Enviroment Two i686
uname -r = 2.6.9-34.0.1.ELhudemem

Let me know what you think.
