Ok.  now we just need to figure out how the ports are mapped. Since
you have two DVI ports I suspect the one you are currently using it
drive by an external tmds chip, which is not fully supported at the
moment (it might work if OF or macos init's the chip first).  That may
be part of the reason for the interference.

try the following connector table:

# port  ddc            dac       tmds     connector
# port0 VGA_DCC primary external DVI-I
# port1 DVI_DCC  tvdac     internal  DVI-I
Option "ConnectorTable" "3,0,1,3,2,1,0,3"

If that doesn't work, try swapping the monitor to the other DVI port.
Ideally we'd work out the analog mappings as well.  Finally, if none
of that works try swapping the ddc ports:

# port  ddc            dac       tmds     connector
# port0 DVI_DCC primary external DVI-I
# port1 VGA_DCC  tvdac     internal  DVI-I
Option "ConnectorTable" "2,0,1,3,3,1,0,3"

the information these numbers correspond to can be found in
radeon_probe.h if you are curious.
