Now I understand your problem. You need a kernel module that isn't loaded yet. So your program tells you to load it. But Easy Debian doesn't have its own kernel, it just uses Maemo's kernel.
Therefore you'd have to load a module that is compatible with the N900's Maemo kernel.
I'm not sure if such a module already exists. After doing a quick search I found this thread:

But it seems to me the modules linked there are for some older Maemo version, maybe for the N800 or 810.
