HW 3d is definitly supported on your hardware.  First you need to make
sure the DRI  is even working at all in single head mode.  once you
confirm that you can get mergedfb working.  your config is wrong for
mergedfb.  it doesn't really work like regular multi-head.  since one
instance of the driver handles both heads it's all done in one device
section.  see the radeon man page for more info.  here's a link to a
sample config as well:

and the man page:

Also for mergedfb to work you need to be running at least xorg 6.8.x;
prior versions did not support that feature.
