That MMU-update is currently only available for the ACA1230, not for the ACA630. The only 1230's that were equipped with MMU were the 56MHz versions, so there's already a small chance that you can make use of it at all (small quantiy of 28MHz cards also had an MMU, but that was only a handful of cards).
The card would have to be sent to Germany, and shipment back with insurance will be in the 20,- EUR range. Since I've made this offer, only one guy has sent his board, and he was from Germany. Seems like the majority of people figures that it's not really necessary.
