  I've never used a 5250 emulation card, but I did use an SNA/3270
emulation card for a while, and a few other strange bits of hardware
under DOS with similar structures.

  The thing is that the memory on the card is a "buffer" space,
addressable from one side by software (which *might* not be too hard
to redirect to another address), and from the other side by
*circuitry on the card*, which interfaces to the communications link.
 Redirecting that circuitry to some other memory would *at least*
require rewriting a ROM, and even then the necessary bus interface
circuitry might not be present.

  Bottom line is, I think you have three basic options:

1.  Replace the card.  5250 is an IBM terminal standard (you did
specify AS/400...), so perhaps your IBM support rep can help.

2.  Repair the card by replacing the failed memory -- this is
probably even harder.  You *might* get lucky -- if the memory chips
are socketed, one or more may have worked loose due to
heating/cooling with each power on/off cycle, and so re-seating them
in their sockets *might* correct the problem.

3.  Try to get enough laptop support for one station working sooner
than February....
