Subject: SEEPROM test patch

James, Robin.  I looked through the patches again and found that the
SEEPROM routines were not being adjusted correctly along with the flash
NVRAM access routines.  The patch below should shore up the difference.
The patch works on both BE and LE systems.

Can you apply the patch below and see if it fixes your problem?  (You
may have to back out David's changes for the mac addresses to be
restored, but 'eeprom -e' dumps should be fixed.)  If it does, I'll
post a replacement patch that documents why the code is doing what it's
doing.
