You're right; I wasn't aware of this.
Hans, you may try to copy the backup bootsector over the bootsector.
Do this under linux as root and make sure you don't have a typo:
cd
dd if=/dev/hda1 of=oldbsect bs=512 count=1
dd if=/dev/hda1 of=backupbsect bs=512 count=1 skip=6
dd if=backupbsect of=/dev/hda1 bs=512 count=1
This should recover your FAT32 partition.
