So with Ubuntu's image losetup-ed and kpart -ax-ed:
sudo file -s /dev/mapper/loop0p1

/dev/mapper/loop0p1: x86 boot sector, mkdosfs boot message display, code offset 0x58, OEM-ID " mkdosfs", Media descriptor 0xf8, heads 64, sectors 144522 (volumes > 32 MB) , FAT (32 bit), sectors/FAT 1112, serial number 0x4c5f659b, label: " "

after mkdosfs -F 32 -H 64 -v /dev/mapper/loop0p1 and copying over the same files:
/dev/mapper/loop0p1: x86 boot sector, mkdosfs boot message display, code offset 0x58, OEM-ID " mkdosfs", Media descriptor 0xf8, heads 64, sectors 144522 (volumes > 32 MB) , FAT (32 bit), sectors/FAT 1112, serial number 0xf049b263, label: " "

If I don't recreate the FS, but just copy over the files, it doesn't work.
