Yes, it appears so, the AC97 was used by an other driver accessing 
non-sound functions on the same chip. I tried disabling the sound/arm 
ac97 part but that gives me no sound cards at all. Currently I have the 
following (with no sound card found):

CONFIG_SND_AC97_CODEC=y
# CONFIG_SND_AC97_POWER_SAVE is not set
CONFIG_SND_PXA2XX_LIB_AC97=y
# CONFIG_SND_PXA2XX_AC97 is not set
CONFIG_SND_SOC_AC97_BUS=y
CONFIG_SND_PXA2XX_SOC_AC97=y
CONFIG_AC97_BUS=y
