i'll try to rephrase what i did for now:

mkdir master/isolinux
mount -o loop boot.img boot
cp -rf boot/* master/isolinux
cd master/isolinux ; mv syslinux.cfg isolinux.cfg
--build 2.4.26-grsec kernel
mv bzImage master/isolinux/vmlinuz

du -h gives me
1.1M    isolinux/vmlinuz (lots bigger then the 2.4.20 kernel i first had 
from knoppix-std) so i guess i need isolinux
*note: i didn't bothered copying 2.4.26 modules cos i thought it since 
most modules are 'insmod -f'-ed, that wouldn't really matter, i gonna 
check with new modules later

build the image:
mkisofs -pad -l -r -J -v -V "Custom KNOPPIX" -b isolinux/isolinux.bin -c 
isolinux/boot.cat -hide-rr-moved -no-emul-boot -boot-load-size 4 
-boot-info-table -o /mnt/hda1/knx/knoppix.iso /mnt/hda1/knx/master
|
|---> this gives me a new bootable cd image which boots 2.4.26 kernel, 
but then loads my old linux


i started with the old knoppix .config for my new kernel.
maybe i could try and rebuid cloop too, but gonna wait some more, maybe 
i get some interesting advice concerning kernel customization

if you happen to find a flaw in what i've written here, please let me 
now, i'm kinda stuck and rebuilding everything takes like too long not 
to get bored with it ;)

thanks,
Thomas
