Are you running the hardware/kernel in 32-bit mode? or 64-bit?
(I don't know what a Dell PE1800 has/does.)
I'm guessing 32-bit due to all of the warnings I see in x86_64 mode.

The problem could be something as simple as the modules don't have
a MODULE_LICENSE() in them. Are you running a RH/FC kernel or your
own custom kernel? I get this when I load them:

ibb: module license 'unspecified' taints kernel.

I can load/unload both of them.
