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.

1. Foloppy always read only after 2.5.12?

When  try to run lilo with a kernel after 2.5.12 to a floppy i get:
Fatal: open /dev/fd0: Read-only file system
Im runnig on a x86 platform with with a AMD K6
to me it seems at an enduser error because knowbody has this problem reported
this or is it realy a bug.
The floppy drive is detected :
May 14 07:09:07 orac kernel: Floppy drive(s): fd0 is 1.44M
May 14 07:09:07 orac kernel: FDC 0 is a post-1991 82077
