You may not need to recompile the kernel, instead compile your driver
only. There are (extensive) instructions for how to do it here:

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:

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

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...

I don't think it would be required.

By the way: when posting to this mailing list, please send e-mails
with text only and not HTML. 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
