I finally managed to figure this out. I used sndconfig with
--noprobe and --noautoconfig and set the mpuirq to 7. Things
kind of work now. A question and an observation:

Could you please tell what these lines from rc.sysinit are supposed
to do?

        # tweak isapnp settings if needed.
        if [ -n "$PNP" -a  -f /proc/isapnp -a -x /sbin/sndconfig ]; then
            /sbin/sndconfig --mungepnp >/dev/null 2>&1
        fi

I got the impression (not completely sure) that this was overwriting 
the changes I made to modules.conf, so I commented it out. The man
page for sndconfig has no documentation for the mungepnp option.

Now I get a "Loading sound module (CS4232)  [FAILED]" message at 
startup, and the modules are not loaded. But when I start Realplayer,
the modules are loaded, interrupts assigned as per modules.conf (vide
/proc/interrupts) and I can hear sound normally.
