[LAU] howto get pcmcia firewire card working

[Bill Gribble]

There were problems with ExpressCard hotplug last I checked.  Getting the kernel to recognize a card when it's plugged in is not possible all the time. Try booting with the card already plugged in and see if it's recognized then. 

Thanks,
Bill Gribble
