The expectation is that new platforms would move over to 
dm9000_initialize_ex(), dm9000_initialize() just being a shim to use 
what used to be #define'd in the board config.h for backwards 
compatibility with older boards.

There's really 3 options that I fought with:

1.) Change dm9000_initialize() to dm9000_initialize(x, y, z).  PATCH #3 
then also includes changes to all of the various boards.

2.) Add dm9000_initialize_ex(x, y, z), make dm9000_initialize() call 
dm9000_initiailize_ex(x, y, z).  No boards need to change.  This is what 
I chose.

3.) Hybrid approach, do #2, make another patch (#4) that moves 
everything over to dm9000_initialize_ex(x, y, z) while renaming it to 
dm9000_initialize(x, y, z).  Seems more round-about than #1 with the 
same end-result, but sometimes I feel like it is a little easier to 
review the meat of this change (#3) without it also dealing with tons of 
board churn.

Thoughts?
