If there was an unused variables I would happily remove that too but the 
'version' string is not unused. The etherh.c and mac8390.c files both 
include "lib8390.c" and in there you'll find the 'version' string used in 
ethdev_setup().

If you want to remove the reference to the 'version' string from the core 
driver, it would seem to imply the loss of this functionality from 8 
modules or else the duplication of this code in the same modules, neither 
of which seems desirable... What am I missing?
