Are both CONFIG_PPC_OF and CONFIG_FB_RADEON_I2C enabled in your .config? I
got bitten by the fact that the latter can only be enabled if CONFIG_I2C=y,
but then I never had exactly the same problems you have.

I don't think it has anything to do with the sound chip but rather with
Oct 11 03:58:40 thor kernel: dmasound: can't request IO resource !
and
Oct 11 02:50:27 thor kernel: ALSA sound/ppc/pmac.c:1092: pmac: can't
request resource 0!
(seems to be related to OF)
