I've realized that I need to open pd with sudo in order to have it work with jack (I also have to open jack with sudo in order to use the firewire).
both the jack server (jackd) and it's clients (pd) *must* run as the same user.
you definitely should *not* use sudo for starting either jack nor pd. find out how to use jack/firewire as an ordinary user (in the relevant forums; or maybe somebody else here can give you advice; me, i don't use firewire soundcards atm).
