Logs and config from various runs.

I need to have 5 monitors in computer. I have three identical PCI-express 
graphic cards radeon X1650 with RV535 chip.

Now I'm trying to configure 3 monitors (because 2 monitors on one card work
well).

On opensuse 11.1, X.Org X server 1.5.2, radeonhd driver 1.2.4, I can get the
picture to two monitors on the same card only. Other drivers don't help -
neither fglrx nor radeon. I can't run two monitors on the second card (only one
card in xorg.conf, but with different PCI ID) - machine freezes. When I take
the third card out, the machine behaves the same.

On opensuse 11.0 with X.Org X Server 1.4.0.90 it is a bit better. I can
configure 3 or 4 monitors via xrandr, but they're in two groups. I have mouse
cursor on one card and can't go to another. When I change resolution on monitor
from the second group, I can work on the second group and can't on the first.
It crashes when I switch xinerama on.

Because there are many combinations (various versions of X, two drivers
(radeon, radeonhd), with and without xinerama, with two or three cards), can
you say me which configuration of sw and HW will be the best for you, please?

I have never compiled xorg, but I'm ready to try it.
