Ah thank you, that will most likely be it. I wasn't able to use fdisk,
because fdisk refused operation on my sd card / sd card reader. Probably
a bug in the card reader itself, as it persists with different micro sd
cards. And fdisk is too picky to continue. What does work is cfdisk, but
of course I didn't know exactly how to translate the line from the
makesd script into cfdisk. I will try to make the correct first
partition on some other block device, and then use dd to transfer it and
the partition table to the sd card. would it make sense to provide
somewhere an image, the partition table and the small FAT partition
ready to copy with dd?

Also, I noticed that the download of the files from your servers was
very slow. Would a mirror be helpful?
