can't locate module sound-service

[Joolz]

When booting my system I allways get these kind of messages in
/var/log/messages:

Apr  4 22:18:59 localhost insmod: insmod: a module named ac97_codec already exists

Sound is working fine though. I've been having this since a long time
(RH7.3 and earlier), but I'm curious if this is normal... I have a
standard FC1 with all updates and nothing "exotic" (like homemade
kernels).

TIA!
