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
from your config.
What patch did you use? also, what version of xfree86 did you patch?
were their any rejects?
Also did you ever get non-mergedfb dualhead working with stock 4.3 or
CVS? If that works then mergedfb should work.

-----------------------------------
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?
