I am a little confused as to how you are testing this :-)

The driver still wouldn't compile on Ubuntu 14.04 with libi2c-dev. The "#if HAVE_LINUX_I2C_DEV_H" won't be satisfied until after config.h is included (typically by main.h). Since the driver won't even be compiled if WITH_LINUX_I2C is not defined, I took out the #if wrapper.

Also, since the intermediate commits aren't terribly useful, I'll collapse the asem_i2c_take2 branch into a single commit before merging to master. Here is the branch as it stands:
