There is no man page at the moment, I suppose I should see about
throwing one together.   It's a driver for generic AT24xxx compatible
I2C EEPROMs.  See src/sys/dev/i2c/files.i2c and src/sys/dev/i2c/at24cxx.c
It provides character device access to the device.

At the very least, one should see if code could be shared.
