How do I update a driver?

[thomasbernie]

I would like to replace orinoco_cs.c  0.12, with a newer version.  I have the
new driver, but can\'t locate the old one (using find).  I\'m new to Linux.  I\'m trying to get Kismet running on my new SL-6000 and I\'ve been told the 0.14 driver may be the answer.  

Thanks in advance,

Tom
