With the stock 2.6.13 (test26.s) kernel I managed to get the cardbus card recognized.
1) Installed the madwifi-ng driver (make and make install).
2) Second add this to my /etc/lilo.conf.

append="irqpoll pci=assign-busses"';

3)Third add -f to the CARDMGR_OPTS= in the /etc/rc.d/rc.pcmcia file. Looks like this.

CARDMGR_OPTS=-f

4) Remove port 0x800-0x8ff and port 0xc00-0xcff from the /etc/pcmcia/config.opts.

5) Reboot and it should work.
