There's a limit to the power available on a pcmcia Firewire port, even
if it DOES have the larger power-carrying socket. There's generally
provision to plug in a wall-wart to the pcmcia card to correct this.
Apart from this, some laptops share resources in a way that enables
successful multiple-stream I/O, some have problems. I don't think the
problem is generally in the card itself these days, unless it's very
cheap or uses a non-standard chip-set. But you still really have to
suck-it-and-see with laptops.
