I'm getting something like "Error: /usr/share/grml2usb/grub/splash.xpm.gz can not be read"!?
[NOTE]
FAT32 is supported since syslinux version 3.0.

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This usually means that the machine you ran grml2usb on had syslinux 3.x
+installed. The version of hdt (Hardware detection tool) shipping with Grml
+2010.12 and newer requires syslinux 4.x.
