The example on that page is far from complete.  Specifically, the 
init_module() function needs to be registered as an init_call - this is 
why your module messages are not being printed.  The module is in the 
kernel, but the kernel doesn't know that it is supposed initialise it.

I recommend you get a copy of "Linux Device Drivers" by Rubini and 
Corbet, or read it for free online http://www.xml.com/ldd/chapter/book/
It is the best reference for device driver development.

Also, look at other drivers in the linux kernel for pointers on how to 
initialise drivers/modules.

It might be worth posting your driver source to the microblaze-uclinux 
list - someone there might have time to look over it.

Regards,

John
