Seems like there is a fix in dosfstools 3.0.15 now:
http://www.daniel-baumann.ch/gitweb/?p=software/dosfstools.git;a=blobdiff;f=src/mkdosfs.c;h=beda76f0fa87c85a6cd3bccb860865eaabc7143a;hp=25c520f972431310b038843a9d3bbd0eeba22fad;hb=b8201b34eb83c2bf87bd1c2b1a7fa57a1dc28191;hpb=7a756385ed6bce393396c699e068b5f239053db6
(Probably not the "right" solution, but I still wonder if it would be worth a backport of this patch?)
