I can not agree. Please check Dave's commit:
http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=23fff28a9b0529869bffef8aab0d3f350dd3b5a4

He just modified r600_audio_chipset_supported which is called from:
1) r600_audio_init
2) r600_audio_fini

But we do not call any of these functions from rv770.c.

Ah, and we use rv770.c (functions from it) for rv770, rv730, rv710 and rv740.
