    I am writing a driver for a TAOS evaluation module. This device is a
    limited SMBus master, connecting to the serial port. The evaluation
    chip is connected to the SMBus. In my case this is a TSL2550 light
    sensor, but virtually all compatible TAOS evaluation modules could be
    supported.

    I2C bus drivers have to be implemented in the kernel, so user-space
    isn't an option for me.

    I just posted a first (working) version of my driver, if you want to
    take a look:
