ac97_codec/es1371 screwy on 2.3.46-2 (pre)

I'm still getting weird oopses when trying various mixer programs with the es1371, on kernel 2.3.46-2, with sound drivers compiled as modules. Attached is an example - still obviously a
problem with the ac97 implementation w/ es1371. I'm still not quite sure why ac97_codec is being used in the first place.
