The problem might not be a Xinerama problem.  I got the same issues when
using fake-Xinerama (I used ldd /usr/sbin/gdm to make sure it was
loading the right .so file.)

I got Twinview to treat my vertical monitors properly, and I used fake
Xinerama to patch them together.  I still got issues with "Invalid input
device pointer".  If I use fake Xinerama without Twinview (four
screens), I still get errors.

I think that the issue has much to do with the physical arrangement of
monitors and the number of screens.  I had my screens configured in such
a way that Monitor 0 and Monitor 2 were on one card, and Monitors 1 and
3 were on the other (I wanted both my large DFPs to have DVI inputs.)

If I plug the screens in such that Monitors 0 and 1 were on one card,
and Monitors 2 and 3 on the other, the issues seem to go away somewhat.
