In file i2c-api.c you can find

*   @file   i2c-api.c
*
*   @brief  This file contains the implementation for performing I2C operations
*           on the gumstix.

that does not look generic...

Anyway: I will create a patch so that the package kernel-module-i2c-dev is 
created.

A bit off-topic: Would you like to test the oe-core version with the meta layer 
found in https://gitorious.org/schnitzeltony-oe-meta/meta-freescale ?
