The ethernet driver might be a little trickier, but not impossible.  
There needs to be a clear separation of "ethernet chip" operations and 
"card the chip sits on" operations.  Register access is likely to be 
different, as well.

In order to really do this properly, the m68k ports should probably 
implement the <machine/bus.h> interface designed by cgd...then, it might 
even be possible to share things like the 8390 driver with the i386 port...
