i2c timeout issue should have been fixed with the following patch:
i2c: i2c-s3c2410: Drop class based scanning to improve bootup time
(commit id: 6031d3dfc73b49bede540872e51a70ee0b6786d4) which is
available on Wolfram's I2C tree (should be part of linux-next too). Also
I do not see I2C_S3C2410 enabled in the config.
I do not have access to h/w today. I can verify and check tomorrow or
somebody could test it in the meantime with the above suggestions?
