The thing I did not explain is that 2.6.31 has no support for the IGEPV2
board. So, to get it working I would need to backport the board support.

However, I can compile a 2.6.33 kernel with a configuration for the
beagle board. To be sure that the configuration works for you, I would
need your .config though.
