Hi Stephan!

What I did was to use the Gnome GUI:

System > Administration > Networking - at the Network Settings window
I chose "Ethernet Connection" and then hit the properties button.  You
will probably see tha DHCP is the current choice - THERE set up your
static address.

Another way to check if DHCP is on:
# Here I use "ps aux" (show all processes) and filter with "grep dh"
which only finds itself (expected):
----------------------------------------------------
tod at tod-desktop:~$ ps aux | grep dh
tod       6470  0.0  0.1   2876   800 pts/1    S+   20:30   0:00 grep
tod at tod-desktop:~$ ps aux | grep dh
dhcp      6722  0.0  0.0   2332   536 ?        Ss   20:36   0:00
/sbin/dhclient3 -pf /var/run/dhclient.eth0.pid eth0
tod       6772  0.0  0.1   2876   800 pts/1    S+   20:37   0:00 grep dh
dh
----------------------------------------------------
# I then went to the networking setup and chose "DHCP" and repeated
the experiment:
----------------------------------------------------
tod at tod-desktop:~$ ps aux | grep dh
dhcp      6722  0.0  0.0   2332   536 ?        Ss   20:36   0:00
/sbin/dhclient3 -pf /var/run/dhclient.eth0.pid eth0
tod       6772  0.0  0.1   2876   800 pts/1    S+   20:37   0:00 grep dh
---------------------------------------------------

Good Hunting!
