2.6.23.9: x86_64: floppy not working: p35 chipset

Trying to format a floppy (2-3 of them) on a GA-P35-DS4 2.0 with a regular Sony floppy on Debian x86_64 with kernel 2.6.23.9:

# fdformat /dev/fd0
Could not determine current format type: No such device
# mformat a:
mformat: Could not get geometry of device (No such device)
#

# cat /proc/interrupts |grep floppy
6: 38 37 39 41 IO-APIC-edge floppy

# dmesg|grep -A1 fd0
[ 52.689487] Floppy drive(s): fd0 is 1.44M
[ 52.704661] FDC 0 is a post-1991 82077

During the 'attempted format'

[34324.175770] floppy0: probe failed...
[34324.575342] floppy0: probe failed...
[34324.974733] floppy0: probe failed...

[34327.771344] floppy0: probe failed...
[34328.170727] floppy0: probe failed...
[34328.570283] floppy0: probe failed...
[34328.969717] floppy0: probe failed...
[34329.369275] floppy0: probe failed...
[34329.768691] floppy0: probe failed...
[34330.168197] floppy0: probe failed...
[34330.168257] end_request: I/O error, dev fd0, sector 0

I've tried a few different floppies, the result is the same. The system is 64-bit only, no 32-bit emulation is enabled using a strict 64-bit-only userland. Has anyone else gotten their floppy drive to work under 64-bit?

Is this just a case of a DOA floppy drive or is something else wrong?

Justin.
