I do not see any contradiction or something :) From Your first post I understand that You already have connected Your encoders to PC via parallel port, but the problem is that it is not fast enough. If You get 5i25 card with a custom firmware so that its pinout matches Your existing hardware setup, then You can read encoder signals in 5i25 card and no rewiring would be needed. The same goes for Gecko drives - with corresponding 5i25 pinout You do not need to rewire anything to feed the step/dir signals to each drive. And as Peter already told, that is not a problem to adjust the pinout of particular firmware.
