Yes, but only with `ruler-mode' in a text-only (no fonts) buffer.

Scrolling `customize' buffers (with font-locked headings, with or without
ruler-mode) is even more broken now:

"emacs -q"   "(setq scroll-conservatively 9999) (customize)" 
    behaves the same as before - recenters the window when it should scroll
    one line

"emacs -q"   "(highline-mode) (setq scroll-conservatively 9999) (customize)"
    HANGS emacs! sometimes C-g can unhang it, usually not.
    Highline is from http://www.cpqd.com.br/~vinicius/emacs/

Maybe a good test case would be even more complicated buffers (for example w3
or the startup screen)
