One clock is for the bus which must be turned on. The other is for the bitclock which we currently can ignore since we only support clock slave mode. On an i.MX5 ssi[123]_ipg_gate must be turned on by the ssi driver. From a quick look to the clock code it looks correct.
I tested audio playback on a mx51evk board last week using linux-next and it worked fine (it has a sgtl5000).
I don't have any hardware with ac97 to try it.
Also, for the playback to work you need to install the SDMA firmware.
