Again - can I ask why?  The sysfs/ interface exists to provide the
right interface to the applications and the user to accomplish what
they want to do.  If you have a good reason for exposing this
functionality, then I'm all ears, but I think that "just for giggles"
doesn't quite cut it.

If you want to write directly on the device for testing purposes, then
the i2c-tools work great - you can bang on the registers all day.
