OK, as an alternative I have a start script which basically contains:

        CS4232_OPTS="io=0x530 irq=9 dma=1 dma2=0 mpuio=0x330 mpuirq=9"
        modprobe sound # loads sound and soundcore
        insmod uart401
        insmod opl3
        insmod adlib_card io=0x388
        insmod ad1848
        insmod cs4232 $CS4232_OPTS
        rmmod cs4232 # it seems it needs to be unloaded and reloaded
        insmod cs4232 $CS4232_OPTS

This solution works good enough to listen to MP3's for hours :-) From time
to time it reports DMA/DRQ problems in the syslog, though. Although the
module stack may seem strange to some folks it _does_ work. I tried about
every other possible combination bun none proved stable so far. Without the
unload/reload of the cs4232 module it doesn't work at all (DMA buffer
allocation errors over and over). 

This is on a 600 (-510/-910). 

Hope this helps.
