No. IDE floppies are a different kind of device, IOmega Zip is one example.
They are attached to an IDE controller, just like a hard disk or CDRom
drive.

Dunno. The kernel driver still uses fd internally. However, here's the
relevant udev rules from Gentoo:
% grep -r floppy /etc/udev/rules.d
/etc/udev/rules.d/50-udev.rules:# floppy devices
/etc/udev/rules.d/50-udev.rules:KERNEL=="fd[0-9]*", NAME="floppy/%k",
SYMLINK+="%k", GROUP="floppy"
/etc/udev/rules.d/50-udev.rules:KERNEL=="fd[0-9]*", ACTION=="add",
ATTRS{cmos}=="*", RUN+="create_floppy_devices -c -t $attr{cmos} -m %M -M
0660 -G floppy $root/floppy/%k"
/etc/udev/rules.d/50-udev.rules:KERNEL=="fd[0-9]*", ACTION=="remove",
RUN+="/bin/sh -c 'rm -f $root/floppy/%k?*'"
/etc/udev/rules.d/50-udev-default.rules:KERNEL=="hd*", SUBSYSTEMS=="ide",
ATTRS{media}=="floppy", OPTIONS+="all_partitions"
/etc/udev/rules.d/50-udev-default.rules:KERNEL=="fd[0-9]",
GROUP="floppy"
/etc/udev/rules.d/50-udev-default.rules:KERNEL=="fd[0-9]", ACTION=="add",
ATTRS{cmos}=="?*", RUN+="create_floppy_devices -c -t $attr{cmos} -m %M -M
0640 -G floppy $root/%k"
But the rule for IDE floppy looks like this:
% grep -r ide-floppy /etc/udev/rules.d
/etc/udev/rules.d/60-persistent-storage.rules:KERNEL=="hd*[!0-9]",
ATTR{removable}=="1", DRIVERS=="ide-cs|ide-floppy",
GOTO="persistent_storage_end"
Bye...
