Have you looked at the howto at this link:
http://www-307.ibm.com/pc/support/site.wss/MIGR-4BP6Q6.html

Also, I think the driver that you need is CS4232 rather than CS4236. My 
experience has been that only one or two distros that I have tried worked 
with the CS4236 module. With RH, you will probably have to unload then reload 
the driver before it will work without the annoying multiple repeat echo 
effect. Disable quickboot if you haven't already. Quickboot seems to cause 
problems with the sound on 600's under Linux.
