Hm, how did you install grml? Inside a running system or from your 
distribution?

I think the problem is that you have syslinux 4 and the files (vesamenu.c32) 
on grml 2010.04 are for syslinux 3. (See http://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=591480)

As a workaround you can try to install grml from a running grml instance. Or 
try to install it to a directory, replace all the .c32 and isolinux.bin files 
in /boot/isolinux with the files from /usr/lib/syslinux/ (debian package 
syslinux-common) and run grml2usb from that directory.


The correct solution for grml2usb could be to overwrite existing modules on 
the disk with the ones from the distribution. Unfortunately this only would 
work for debian based distributions. Or we can just ignore it as this happens 
rarely. But currently we have different isolinux versions in stable and 
testing and they require different modules...

Thanks for your bugreport,
Ulrich
