Your log looks fine. Direct rendering seems to be enabled. Whether or not DRI gets enabled shouldn't have anything to do with MergedFB.
try removing: Option "AGPMode" "4" and: Viewport 0 0
Tried removing them, same situation.
from your config.
What patch did you use? also, what version of xfree86 did you patch? were their any rejects?
No patch, took the binaries.
Also did you ever get non-mergedfb dualhead working with stock 4.3 or CVS? If that works then mergedfb should work.
I'm using 4.3 from RH9.
Do you think compiling from CVS should work better? If yes -- should I checkout the CVS, then patch, and then compile? If so -- could you write down the URL for the mergedfb patch again?
Thanks.

-----------------------------------
Moving on... I install kernel 2.6-test5, which is supposed to have better via-agp support.
Now when I start X the second monitor simply stays black. However -- it's power-led is lit, which means some information is moving from the computer to the monitor (in console mode the second monitor's power-led
is off, as in stand-by mode).
Attached is my current XFree86 log. I manually made sure that the
radeon module and the via_agp module are loaded.
Any thoughts?

Well, MonitorLayout didn't change anything. I think the problem is

to the agpgart.o module not loading. Apperently there's a problem
with
KT400/600 AGP and agpgart.o -- the mainboard uses AGP 3.0, and
agpgart.o
doesn't support it in this version.
Does anyone know in which kernel version agpgart.o supports KT400 AGP
correctly?

in regards to the weird behavior, you might also want to disable fastwrites.
The behavior you are seeing when you switch modes (ctrl-alt-+) is expected. you are swithing between a side by side mode (1024x768-1024x768) and a clone mode (1024x768). in the clone mode
the
both viewports look into the same part of the framebuffer.
you can try adding:
Option "MonitorLayout" "CRT, CRT" if you are using two CRT monitors. if you are using a DVI flatpanel and a CRT then try:
Option "MonitorLayout" "TDMS, CRT"
you can also try changing "CRT2Position" from "LeftOf" to "RightOf" it shouldn't make a difference, but it's worth a shot.
