Help to revert from KDE 4

[R. G. Newbury]

In attempting to get out of dependency hell while installing mplayer, I 
apparently upgraded my Fedora 8 desktop from KDE 3.5 to KDE 4.0.

HELP!...KDE 4 is a bloody disaster. At the moment, I have no KDE "Start" 
icon, no panel, and worse yet, NO KONSOLE. I eventually found that I can 
start an xterm, by using the 'Run' command, but xterm is not konsole. 
The screen appears unstable too...

WHAT IS THE NAME OF THE KDE 4 RPM? So I can uninstall it. And what is 
the name of the kde 3.5 rpm. And what do I do to revert the packages 
which were also upgraded in lockstep.

And yes, I have no banished the fedora-development.repo file.
