That really is a separate problem.  We *could* do this with a board
 specific powerpc machine driver, but I don't think it is the best
 solution.

 I'm still thinking that the drivers module_init() function could check
 the top level board model property and decide whether or not to load
 based on that.

You're assuming the driver is compiled in.

If the drivers are on initrd selection has to happen via the normal
device/driver matching process. Search for a device in the alias table
of the drive file.
