Glad I/we could help!
I manually installed Xfree86 4.4.0 to Mandrake 10.0. For the most part, the installation was successfull -- my X server/session behaved properly, loaded KDE, ran 3d games (via the Nvidia drivers), etc. There were a lot of little pecularities -- screen flickering when moving between consoles, weird outputs when shutting down the server, etc. In the end, I decided it was just as good to stick with 4.3.0.
I agree with vectordrake's disseration
