KDM -> GDM Migration?

[Kagenin <kagenin cyberspace org>]

Hey.  I've downloaded and installed the Necessary RPMs for Gnome.  I am
running Caldera OpenLinux 2.2 with a 2.2.12 Kernel.   I'm sick of looking
at KDE.

Caldera makes KDM the default Login screen.  I'd like GDM there instead.
Unfortunatly I cannot find an docs for making a system-wide KDE->Gnome
Migration.  I don't suppose anybody could lend a hand?

Thank you for your time,
Kagenin
