Well, that's a good reason for it to stick around, right?

Good point, I've sent my patch for lm75 to the list.

It looks like the binary files for sysfs support isn't as easy when you
are in the driver model, so it will take a bit longer to add that
support (need to add some driver core wrapper support first).  But that
is the way the eeprom driver should move to.
