A priori, nothing in the -3 upgrade could have induced that behavior. Maybe in
the -2 upgrade, but if it was working...

Anyway, dual-head and xinerama are dead now that xserver 1.4 is out, it's
replaced by randr 1.2 (not for every drivers but...).non-xinerama dual head is
dead completely, AFAIK, so it may be your problem. Maybe your driver isn't
randr-aware but there was some changes in the xserver.

You could try with Xfce running with another window manager to test, too.

I'm reassigning to xserver-xorg but feel free to get back to us at
pkg-xfce-devel at lists.alioth.debian.org.
