oh - yes:

Mar 23 09:12:20 opensuse103 kernel: ac97_codec: module license 'unspecified' taints kernel.

modinfo ac97_codec
filename:       /lib/modules/2.6.25-rc6-git7-default/kernel/sound/oss/ac97_codec.ko
srcversion:     8665939D5E471F7E331BB3E
depends:
vermagic:       2.6.25-rc6-git7-default SMP mod_unload 586


seems MODULE_LICENSE is missing in ./sound/oss/ac97_codec.c !?

do you mean this one ?

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=55ff1aba940ff46d4f6d4fd790ea3e1a47aaa84f

ok, it may be sort of "dumb" to blindly load one module after the other but i would expect a more meaningful message.
