It looks like the vertical scrollbars are the culprit for the 2 sec
page scroll.  I turned them off and Emacs became usable again.
Startup still takes forever though.

Apparently the GTK+ scrollbars in Emacs 22 are very heavyweight.  The
Emacs 21 I was using was built with the X Toolkit scrollbars and it
works much better for remote X11 usage.

Interestingly, the -D and --basic-display startup options don't seem
to have any effect on the scrollbars; Emacs starts up with a
heavyweight display always.

I miss the lightweight scrollbars so I guess I'll have to build Emacs
22 or 21 myself.  I'll probably stick with 21 since it seemed to start
much faster.
