uname  -a gives:

Linux linux-8c8n 2.6.18.8-0.9-bigsmp #1 SMP Sun Feb 10 22:48:05 UTC 2008 i686 athlon i386 GNU/Linux

I tried using the same settings, 
http://lapoc.de/img/qjackctl.png
which failed, at first but ...

I got it working  by changing  periods buffer from 3 to 2 (soundblaster live value)
And switching realtime off. (when I try to change them, Jack wont start anymore.

This is what the message windows tells us:

Hi Guus,

Hi all

I  re installed jack and qjackctl.
(Suse 10.2 default kernel)

This did help a bit: when typing - - version, I now get:
 
jackd version 0.109.2 tmpdir /dev/shm protocol 22
    

The jackd-version is OK. what says:

uname -a

?

  
 qjackctl still says it can't start jack.
    

Open the "settings"-window in qjackctl and make it look like this:

http://lapoc.de/img/qjackctl.png

Then hit "Start" and post, whats in the "messages"- window.

  
Desperate, I went to the command line, and to keep it short, I tried
(not as root):

jackd -d oss
    

Forget about this oss-crap, please - it is only needed on older I-Books
to make jack barely work. In any other case the alsa-driver (-d alsa) is
better.
