ALSA (and kernel?) problem

[Alex <alexn@telia.com>]

I'm running kernel 2.4.20 and have recently got a abit kd7 with
an onboard audio chipset.

The chipset on the motherboard is via vt8235.

I just downloaded the latest alsa ( 0.9.0rc6 developer) version of alsa as i 
couldn't see the kernel supporting this chipset.

did everything according to:
http://www.alsa-project.org/alsa-doc/doc-php/template.php3?company=VIA&card=&chip=via8235&module=via82xx

i'm a debian user, when coming to modprobing:
tudor:/etc# modprobe snd-via82xx
/lib/modules/2.4.20/kernel/sound/acore/snd.o: unresolved symbol _mmx_memcpy
/lib/modules/2.4.20/kernel/sound/acore/snd.o: insmod 
/lib/modules/2.4.20/kernel/sound/acore/snd.o failed
/lib/modules/2.4.20/kernel/sound/acore/snd.o: insmod snd-via82xx failed

CONFIG_SOUND was compiled into the kernel.

searched some on google but found no useful information,
i'm thankful for all help.
