Please further ellaborate here.
Is it that you need to replace the EEPROM every time you power down the
card? This sounds very unusual.

Bring it to the Linux Expo, I'll take it apart.

The only problem along these lines I have encountered was while writing
to registers on a development ethernet board at work in which the magic
sequence for writing required (most hardware has a magic sequence of
accesses necessary to convince it you really want to program it) was hmm
basically non-existent so it was trivial to completely trash whatever
was on the flash. I've not seen this with EEPROM based cards.
