After doing some more of the good old try&error, I found the following
solution:

shared-network faw-net {
  subnet 192.168.0.0 netmask 255.255.255.0{
    option broadcast-address 192.168.0.255;
  }

  subnet 192.168.1.0 netmask 255.255.255.0{
    option broadcast-address 192.168.1.255;
  }

  subnet 153.95.169.0 netmask 255.255.255.0{
    option broadcast-address 153.95.169.255;
  }
}

The shared-network did the trick. Putting the groups withinh the subnet
seems not to be neccessary, but I will do some more tests.

Regards,
Marco Schwarz

You should be able to declare each subnet like this, but you need your 
group declarations within each subnet as well, I think this example 
should work:

subnet 192.168.2.0 netmask 255.255.255.0 {
        range 192.168.2.2 192.168.2.125;
  group  {
     use-host-decl-names                  on;
     option dhcp-server-identifier        192.168.1.1;
     next-server                          192.168.1.1;
     option subnet-mask                   255.255.255.0;
     option routers                       192.168.1.2;
     option broadcast-address             192.168.1.255;
     option domain-name-servers           192.168.1.126;

     host ws001 {
         hardware ethernet       XX:XX:XX:XX:XX;
         fixed-address           192.168.1.2;
         filename                "/lts/2.4.22-ltsp-1/pxelinux.0";
     }

}
