Loading an intermediate object file.  The correct one is 'ethfoo.o'.

There isn't...  Once loaded, modstat will tell you the major number in
the 'Offset' column.

The command to load the module is simply
'modload <wherever it is>/ethfoo.o'.  -s, -x are optional, -e should
not be needed (if you think you need it, you're doing something wrong).
