I checked that. 2.6.22-14 is in tftp and is created.
vmlinuz is this version but the date is from October.
initrd.img is todays date

You are absolutely right with the 2nd dhcp - thats where i am stuck for
month!!
Where can I change the dhclient behaviour?
Under Feisty it was the -p 1068 Option in the nfs-script. Then I had to
run mkelf-linux and created 
nbi.img-2.6.22-14-386, vmlinuz-2.6.22-14-386 and
initrd.img-2.6.22-14-386 ( with Feisty kernel numbers)

Now it seems only initrd.img-2.6.22-14-386 is changed:

root at edubuntu:/var/lib/tftpboot/ltsp/i386# ls -l
-rw-r--r-- 1 root root   75391 2007-10-15 03:35 config-2.6.22-14-386
lrwxrwxrwx 1 root root      24 2008-01-30 16:06 initrd.img ->

-rw-r--r-- 1 root root   13552 2007-12-21 14:05 pxelinux.0
drwxr-xr-x 2 root root    4096 2007-12-12 22:06 pxelinux.cfg
lrwxrwxrwx 1 root root      21 2008-01-30 16:06 vmlinuz ->
vmlinuz-2.6.22-14-386
-rw-r--r-- 1 root root 1696312 2007-10-15 03:35 vmlinuz-2.6.22-14-386

Booting up to the second dhcp-request works fine.

How does the client get a ip at the 2nd step????????

thanks toni

ps

a part of the dhcp.conf. - maybe this gives any clou:

option option-128 code 128 = string;
option option-129 code 129 = text;

subnet 192.168.2.0 netmask 255.255.255.0 {
  range 192.168.2.80 192.168.2.99;
  option domain-name "kaser.local";
  option domain-name-servers 192.168.2.1;
  option broadcast-address 192.168.2.255;
  option routers 192.168.2.10;
  option subnet-mask 255.255.255.0;
  option option-128 e4:45:74:68:00:00; 
  option option-129 "DPORT=1067";
  next-server 192.168.2.10;

  if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
    filename "/ltsp/i386/pxelinux.0";
  }
  else{
    filename "/ltsp/i386/nbi.img";
  }
  option root-path "192.168.2.10:/opt/ltsp/i386";
