I still don't understand. Simplistically spoken, `pop-to-buffer' is
`display-buffer' + `select-window'. How can, using Sawfish say,
`display-buffer' switch focus and `pop-to-buffer' not switch focus?

We should fix it this time. Please try again two things with the
window-managers you listed above and `pop-up-frames' non-nil:
- tell whether `display-buffer' does switch focus.
- tell whether `pop-to-buffer' does switch focus.
- try both, if possible, with click-to-focus and a focus-follows-mouse
settings (maybe you have to set the value of the Emacs variable
`focus-follows-mouse' appropriately).
Here on Windos XP with a focus-follows-mouse policy, `display-buffer'
and `pop-to-buffer' both switch focus. IIRC, people reported troubles
with the standard click-to-focus policy. Honestly, I'm a bit reluctant
to try out click-to-focus here, maybe someone else can try?

I suppose we should introduce a customizable variable which allows to
call `select-frame-set-input-focus' (or something similar) at least in
`pop-to-buffer' but maybe also in `display-buffer'. But we should also
provide a doc-string recommending what setting this variable should have
on which platform.
