This has been discussed here on LKML before. The preliminary patch at
<http://www.csd.uu.se/~mikpe/linux/patches/2.5/patch-fix-floppy-2.5.16>
fixes the problem for me, but it may not be the "real" fix.

If you intend to mount the floppy as a file system you may also have
to patch fs/partitions/check.c:check_partition() similarly to how
fs/block_dev.c was patched. I haven't tested that bit yet.
