the board running out of EEPROM right now with the IBM Open Shell always
there?  I have sifted through the documentation a bit, but haven't found a
straight answer as to exactly how the board is setup right out of the box.

If you built a standard U-Boot 440GP config, odds are that it will work fine.
If you have a flash programmer, you can always save a copy of the OSOpen
image and then reflash with that if U-Boot doesn't come up right.

I'm not sure if your board is using the EEPROM, but that's only used for
strapping anyway.

Any sort of help is appreciated.  I am extremely new to ICE, JTAG and such
embedded systems -- so please, be patient with me (if you can).

The first thing I would recommend you do is to get a BDI2000 JTAG
debugger.  If you're going to be doing any serious work on U-Boot,
Linux, etc. this is one of the most valuable tools you can have.
