There are (extensive) instructions for how to do it here: http://wiki.centos.org/HowTos/BuildingKernelModules If building the driver without adding it to the kernel does not work, and you really think you should build a new kernel package that includes the driver, see these instructions instead: http://wiki.centos.org/HowTos/Custom_Kernel > and rebuild the initrd.img. This should be a matter of running "mkinitrd" with the right parameters. If you include a line for your driver in /etc/modprobe.conf it should be included in new initrd.imgs by default. > Where do I copy the file in the kernel sources? > I currently have it in a sub folder of the drivers directory in the kernel > source folder. This would be usually said in the driver's documentation, but what you said implies there is none... If that works for you just go ahead... > There is one more question if I may, it does not have a xxxx.h (header file) > do I need it? The driver does compile perfectly without it.

This is the first requirement in Guidelines for CentOS Mailing List, see this page: http://www.centos.org/modules/tinycontent/index.php?id=16. Your e-mails also include a silly disclaimer which I believe was already topic of discussion a little while ago. If you can't control HTML format, company logo image and disclaimer in your company's e-mail address, I strongly suggest that you get a free e-mail account (I use and recommend GMail) and subscribe to the lists using that address instead.
