Running RedHat 8.0, installed the system driver RPM, and everything works fine, except for the sound....

relevent lines in modules.conf:

alias sound-slot-0 i810_audio

It was at sound-slot-1, then 0, neither work. lsmod dosnt show it loaded, and if i try to insmod i810_audio I get:

insmod i810_audio
Using /lib/modules/2.4.18-14/kernel/drivers/sound/i810_audio.o
/lib/modules/2.4.18-14/kernel/drivers/sound/i810_audio.o: unresolved symbol ac97_probe_codec_R84601c2b
/lib/modules/2.4.18-14/kernel/drivers/sound/i810_audio.o: unresolved symbol ac97_set_adc_rate_R5307368c
/lib/modules/2.4.18-14/kernel/drivers/sound/i810_audio.o: unresolved symbol ac97_set_dac_rate_R42924aaa

Any Ideas?

Try this before, modprobe ac97_codec, because you need this to make nvaudio module working.
