NeoMagic 256AV Audio

I have a Japanese laptop which is only sold in Japan, which means I don`t know much about the hardware outside of what Slack 9 and the BIOS tells me. Slack 9 auto-detects a NeoMagic 256AV sound card, loads the modules, but gives an error in dmesg:

NeoMagic 256AV/256ZX audio driver, version 1.1p
PCI: Found IRQ 9 for device 00:14.1
NM256: This doesn't look to me like the AC97-compatible version.
You can force the driver to load by passing in the module
force_ac97 = 1

More likely, you should be using the appropriate SB-16 or
CS4232 driver instead. (If your BIOS has settings for
IRQ and/or DMA for the sound card, this is *not* the correct
driver to use.)

I couldn`t find any information about the IRQ or DMA in the BIOS, and the SB and CS4232 modules don`t load. They give errors similar to this:

/lib/modules/2.4.21/kernel/drivers/sound/cs4232.o: init_module: No such device
/lib/modules/2.4.21/kernel/drivers/sound/cs4232.o: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.21/kernel/drivers/sound/cs4232.o: insmod /lib/modules/2.4.21/kernel/drivers/sound/cs4232.o failed
/lib/modules/2.4.21/kernel/drivers/sound/cs4232.o: insmod cs4232 failed

The laptop model is Fujitsu Biblio Lifebook FMV-6333 MF4/W according to the case.

PS: lspci returns:

Well you could have found the solution by reading your lspci.. but,, I'll point out the obvious for you.

00:07.3 Bridge: Intel Corp. 82371AB/EB/MB PIIX4 ACPI (rev 02)

Acpi... recompile the kernel to support acpi features, or ditch it and head for suse linux
