Actually I can't help, but I'm stuck with the same problem:
media:/ ioslave mounts for example my usbstick if I click on it, but
doesn't show anything when it is trying to load the contents of
media:/sda1, although it's mounted correctly on /media/sda1.
There is a bug filed in bugs.kde.org at
http://bugs.kde.org/show_bug.cgi?id=113349 but it's closed as INVALID
with the conclusion it is a Gentoo related packaging issue of HAL and
DBUS.
My setup is Udev-070-r1 , Dbus-0.50-r1, Hal-0.5.4 and KDE-3.5.0_rc1
The hal-device-manager shows the property of the mounted usbstick as
"volume.is_mounted = false". That's why media:/ doesn't get it.
