Version:            (using KDE 3.5.8)
Installed from:    Gentoo Packages
Compiler:          gcc 4.1.2 (Gentoo package) 
OS:                Linux

On both Gentoo running KDE 3.5.8 and Fedora running KDE 3.5.6 (both using distributor packages), floppy drives do not show up in media:/ (or in the media applet, etc.)  Manually entering "media:/fd0" does work, as does manually creating a device icon on the desktop pointing to /dev/fd0.  If I disable HAL, and I have an entry for the floppy drive in /etc/fstab, everything also works.  In that case, the icon even displays in media:/ as expected.  I tried both with and without the floppy drive in /etc/fstab file while using HAL, and it didn't make a difference.

It appears that all the settings are correct for KDE to be able to mount the floppy, it just isn't showing up.  (I did try with the media applet making sure the "Unmounted Floppy" checkbox was checked, and it made no difference.)  I noticed that the HAL device (/org/freedesktop/Hal/devices/platform_floppy_0_storage) has is_volume set to "false", but according to some Googling it appears this is the intended behavior of HAL.  Perhaps this is causing a problem for KDE?

Here is the output of a couple HAL commands:
