Hi Darsha!

Cool, thanks for investigating! I wasn't aware of the version trick at syslinux 
3.63+. :) I identify the isolinux/syslinux version using strings:

# strings ../grml_cd/boot/isolinux/isolinux.bin | grep ISOLINUX
ISOLINUX 3.61 Debian-2008-02-05

Is there any chance that you rebuild the ISO using a more recent syslinux 
version? (If not please ping me.) I'm afraid of changing the syslinux version 
within the freeze time of the upcoming stable release because we had serious 
problems with more recent isolinux/syslinux versions already. :-/ But I'd like 
to update to a more recent syslinux version shortly after the stable release 
came out.

thx && regards,
