[sisela] problem with two PCMCIA cards

Hi, I have an old laptop (Soyo PW980) that I want to use as a wireless bridge. It doesn't have an ethernet port but it has two PCMCIA slots. My plan was to plug a ethernet card in one of the slots and the wireless card on the other. Now, if I plug either of these cards by itself, then sisela recognizes the card and everything works. However if I plug in both cards then only one gets recognized. Is there a workaround this problem? Thanks, Felipe
