Yes. I had the same issue and got the alsa drivers working by manually configuring. You need to get the options just right.
Try this in your /etc/modprobe.conf
options snd-cs4236 isapnp=0 cport=0x538 port=0x530 sb_port=0x220 fm_port=0x388 irq=5 dma1=1 dma2=0
alias snd-card-0 snd-cs4236
install snd-cs4236 /sbin/modprobe pcspkr && /sbin/modprobe --ignore-install snd-cs4236 && /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-cs4236 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-cs4236


And I forgot to mention you need to modprobe snd-card-0, then go into the mixer and set sound levels so everything is audible instead of turned down to zero.

I had a similar problem with my ISA SB AWE64 board. While I don't doubt that (a variation of) your solution above would work, I found it much easier to config the kernel with built-in sound rather than modules. Works just fine, of course. It's not likely I'm going to change my sound card every few days and re-boot.
