"Good books or ressources ?"
If you want to learn more about some basic features of modules, drivers, etc...
and you have at least a bit of basic knowledge on the C-programming language
read the book _The Linux Kernel Module Programming Guide_ by Ori Pomerantz.
Perhaps it's also contained in your WOODY (woody?)-Linux CDs as a pdf-file.
You will be able to write, compile and load your own kernel module -
well very simple examples - after a short time.
