Even "name" and "power" are, so I think this excludes any driver-specific cause. I'd like you to move around in /sys/bus/i2c and see if each other file/dir has 777 permissions. Also, see in the rest of /sys if there are non-i2c-related directories with the same anomaly. Second, try to write a value to an ordinarily-writable i2c file such as temp_max1. Echo 61000 to it, and cat it to check if the write was successful. Third, could you reproduce the problem with a non-mm kernel (2.6.2-rc1 for example).
