For pc yes, for laptop you don't. Firewire in laptops will always work fine, cause they been made to work specially for that laptop.
Only for pc's there is a trial and error - I had to try 4 different firewire cards myself to find working one and it's not texas.
Anyway all external Interfaces will work just fine with your laptop, M-Audio, MOTU...
my friend from http://centrala.pro/ is using MOTU by firewire in his studio with normal pc and with his crappy old laptop when he's playing concerts (laptop, motu, Live and mpc40) - never complained, never had any issues during live act's.
