virtualbox freebsd 9.1 guest, mouse not operational

[Norbert Beckmann]

Environment:
(Host OS: Solaris 11.1)
VirtualBox 4.6.2 (r82870)
Guest: FreeBSD 9.1-RELEASE (#0 r243825)
Gnome 2.32

I did a fresh install of FreeBSD 9.1 in VirtualBox. Runs fine so far and,
after capturing the mouse pointer on black screen, copy/paste works too.

Then I installed Gnome 2.32, following all the instructions at
http://www.freebsd.org/gnome/docs/faq2.html#full-gnome.
Btw, "pkg_add -r gnome2" did not work.(??) So I had to compile.

Then I installed the guest additions, following all the instructions at
https://wiki.freebsd.org/VirtualBox, chapter "Installing Guest Additions
for FreeBSD guests". After the make, I called X -configure and moved a
modified copy to /etc/X11/xorg.conf as proposed, and performed all the
other things mentioned at that page.

Problem: Mouse is not operational in FreeBSD:
Gnome disabled and calling X, I get a black screen, the mouse pointer
disappears, and I also cannot capture it manually.
Gnome enabled, I get a proper gnome login screen after boot, the mouse
pointer is there, but does not affect something.

Extra attempts (no success / no harm):
in /etc/rc.conf: enabling hald, dbus, mouse.
in /usr/local/etc/hal/fdi/policy/ in addition to 90-vboxguest.fdi, adding
10-mouse-sysmouse.fdi from /usr/local/share/hal/fdi/policy/10osvendor.

Remark: no mouse problems with other guests.
Attachment: /etc/X11/xorg.conf followed by /etc/rc.conf

Any ideas, hints?
