	A long reply because of debug data.

	Evidently during normal operation the CHIP uses these bits to
 control itself.. and upon a soft reset or a non power-up reset these
 bits are undefined. NOW I guess if not cleared the CHIP goes funny.

 One thing to note.  If in /etc/conf/modules I config options to force
 10base2, whether it is the patched driver or not, in reality the UTP
 fails to actually work.. even though the link light is one and traffic
 is around.

 If I connect to a hib or switch via UTP and force the option, the driver
 starts working after about a 15 second delay..  

 HERE IS THE DEBUG from a non modified driver (IE the patch above)
