pcmcia network card lockup

Hi im a relative newbie been using Linux for about 4 years, so i can mess things up pretty good now. :D The laptop is a Toshiba S103 I had Mandrake 9.0 working with a custom kernel and newest pcmcia-cs. After doing a Knoppix 3.2 knx-hdinstall my Netgear MA401 wireless card only works if its inserted before booting. If removed after booting or inserted after booting the machine hangs solid no ctl+alt+bkspc no ctl+alt+del. I have to hold powerbutton in till it dies then reboot. Any idea how to fix this?
Thanks
