>From what I understand about the way the TDM400 cards work, it may be
possible to disable the interrupt on one card and service both cards on
the remaining interrupt. There may be some extra (hardware?)
synchronisation required between the two cards, which would make the
idea a bit less attractive.

This only solves the problem of interrupt availability/sharing though,
not the fact that you still have to do approximately the same amount of
work per interrupt.
