Well, the data sheet of CS4297A says it is an AC97 2.1 compatible codec
while cs4280.c use it as AC97 1.03 codec. Is there any difference
if you comment out the line
1628: /* XXX should not be here */
1629: #define SERACC_CODEC_TYPE_1_03
in cs4280.c ?
Anyway, I will look the data sheets in this weekend.

The changes to cs4280.c was just committed to main trunk and
pulled up 1.5-release branch. You should add
midi* at clcs?
to your kernel configuration file.
