i agree, that code is terrible.  however, those code paths can be trivially 
merged without the proposed bloat yours brings in.  further, that code base 
isn't even used by the ne2000 driver.

so again, the question stands: what exactly do you need to do different ?  
looks to me like the DP_* macros should get punted in favor of io.h accessors, 
and the register offsets rewritten into C structs.
