2.5.34-bk floppy weirdness

The following appeared with the latest bk updated kernel. It was not
present with the 2.5.33 version, nor with a 2.4 kernel version.

I cannot dd to the floppy until either it has been mounted, or until the
superuser has dd'd to the floppy. The following is from a fresh boot:

[tmolina@dad testfloppystable]$ ls
floppy floppyimage
[tmolina@dad testfloppystable]$ ls -l /dev/fd0
brw-rw---- 1 tmolina floppy 2, 0 Apr 11 09:25 /dev/fd0
[tmolina@dad testfloppystable]$ ls -l
total 1448
drwxr-xr-x 2 tmolina tmolina 4096 Dec 31 1969 floppy
-rw-rw-r-- 1 tmolina tmolina 1474560 Sep 1 09:49 floppyimage
[tmolina@dad testfloppystable]$ dd if=floppyimage of=/dev/fd0
dd: opening `/dev/fd0': No such device or address
[tmolina@dad testfloppystable]$ su

[root@dad testfloppystable]# dd if=floppyimage of=/dev/fd0

[root@dad testfloppystable]# exit
exit
[tmolina@dad testfloppystable]$ dd if=floppyimage of=/dev/fd0
2880+0 records in
2880+0 records out
[tmolina@dad testfloppystable]$ ls -l /dev/fd0
brw-rw---- 1 tmolina floppy 2, 0 Apr 11 09:25 /dev/fd0
[tmolina@dad testfloppystable]$

>From a subsequent fresh boot I get:

[tmolina@dad testfloppystable]$ dd if=floppyimage of=/dev/fd0
dd: opening `/dev/fd0': No such device or address
[tmolina@dad testfloppystable]$ mount /dev/fd0
FAT: Using codepage iso8859-1

[tmolina@dad testfloppystable]$ ls -l /mnt/floppy
