Responding to my own post, here's how I got ALSA to work on my Thinkpad
600E.

1. Blacklisted snd-cs46xx _AND_ cs46xx
in /etc/hotplug/blacklist.d/alsa-base (cs46xx is there, but snd-cs46xx
is not.) This prevents /etc/hotplug/pci.rc from loading the CS4610/11
PCI driver it thinks is necessary during boot.

2. In /etc/discover.conf I added the following two lines (but I don't
think they had any effect; Step 1 seemed to have more impact.)
skip snd-cs46xx
skip cs46xx

3. Now, during boot, nothing is loaded, although /etc/hotplug/isapnp.rc
attempts to load cs4232, but it too is blacklisted (by default). At a
terminal after logging in, 'sudo modprobe snd-cs4236' did not work until
editing /etc/modprobe.conf to include the following.

alias char-major-116 snd
alias char-major-14 soundcore
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
options snd  device_mode=0660
alias snd-card-0 snd-cs4236
alias sound-slot-0 snd-cs4236
options snd-cs4236 port=0x530 cport=0x538 isapnp=0 dma1=1 dma2=0 irq=5

(This was stolen from my earlier config, ALSA 1.05 under a 2.4.27
kernel.)

To get OSS emulation working, modprobe 'snd-mixer-oss' and 'snd-pcm-oss'
was necessary. Now everything "sounds" great. 

More work will be necessary for this to happen automatically, and most
likely there will be further problems when hiberation and suspend are
tested. But I'm happy sound works and hopefully this helps anybody else
in a similar situation. I have no idea how Ubuntu might have recognized
and dealt with the situation more appropriately though.
