I have gotten this to work on a thinkpad 600e 2645 5au. I can get sound working on my laptop but only with OSS. I cannot get ALSA to work at all. However OSS sounds and works fine. I use OSS with ESD for sound on my laptop. Here is how:

1. I downloaded this ISO Image that loads dos and has thinkpad configuration options for dos. ps2.exe is the name of the program on the iso. I disabled the onboard modem. I could not get it to work anyway, and got the exact configuration, irg, dma, io etc about the cs4232 sound card. Alternatively you could download and install the Thinkpad Configuration Tools. This is a linux tools that does basically the same thing. It is up to you to choose which to use.

2. It does not matter which kernel you use 2.4.x or 2.6.x Just make sure that you have cs4232 compiled as a module. If you compile the driver into the kernel you will only get clicks and static from the speakers.

3. I did not set the modules to load in /etc/rc.d/rc.modles or /etc/modules.conf. For some odd reason I get the same weird popping sounds as you do with the driver compiled in. I am not sure why. I found a script on the Linux on Laptops website and I use that to start sound. I created the script and then call it from local.start or rc.local depending on your distribution.

Here is the script

#!/bin/sh
#
# sound - start sound subsystem modules
#
# 2002-12-30,jtk

case $1 in

start)
echo "Starting sound subsystem..."
# /sbin/modprobe isa-pnp
/sbin/modprobe ad1848
/sbin/modprobe uart401
/sbin/modprobe cs4232 io=0x530 irq=5 dma=1 dma2=0 mpuio=0x330 mpuirq=9
;;

stop)
echo "Stopping sound subsystem..."
rmmod cs4232
rmmod uart401
rmmod ad1848
# rmmod isa-pnp
;;
*)
echo "Usage: $0 {start|stop}"
exit 1
;;

esac
exit 0


I hope that this helps out anyone with a Thinkpad 600 series.

Expand got feedback?
