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. > Oh...I forgot sound has a weird behaviour: whatever sound module I > use, (snd-powermac, or dmasound_pmac), whenever the module is > unloaded, the sound chip is "dead", and no device can be found by both > modules. 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!
