Hot dang... finally got Moveable Type 2.0 installed and working, just days after setting up the new server. I guess waiting for the new machine was the right choice -- setting up MT on Mandrake 8.2 was a ton easier than on the older versions of this distribution.
Now all I have to do is actually make a new template, one that's compatible with MoveableType. I think it will be better to rework the generic one into a new style, rather than trying to mangle my old template into this system. We'll have to see....
