I was trying this last night to setup Left-of - both my monitors are the same
resolution and use EDID so I don't know if this will help but it might.

After some fiddling I used this in my xorg.conf to identify the monitors:

Section "Device"
        Identifier      "Radeon"
        Option          "UseFBDev"              "true"
        Driver          "ati"
        Option          "Monitor-VGA"           "E481"
        Option          "Monitor-DVI-0"         "H481"
EndSection

It wasn't obvious what text to use after 'Monitor-'.

So try Monitor-VGA without the -0

you haven't posted a log - my log file contains:
(II) RADEON(0): Output VGA-0 using monitor section E481
(II) RADEON(0): Output DVI-0 using monitor section H481
which shows the Monitor-outputname is working.

HTH

If it does then I think the bug is with the driver since the man page says:
  Option "Monitor-outputname" "monitorsection"

and yet the driver output says:
(II) RADEON(0): Port0:
 Monitor   -- AUTO
 Connector -- VGA
 DAC Type  -- Primary
 TMDS Type -- None
 DDC Type  -- VGA_DDC
(II) RADEON(0): Port1:
 Monitor   -- AUTO
 Connector -- DVI-I
 DAC Type  -- TVDAC/ExtDAC
 TMDS Type -- Internal
 DDC Type  -- DVI_DDC
(II) RADEON(0): Port2:
 Monitor   -- AUTO
 Connector -- STV
 DAC Type  -- TVDAC/ExtDAC
 TMDS Type -- None
 DDC Type  -- None

I think the driver should output:
 Outputname  -- VGA
and
 Outputname  -- DVI-0

since I've read here:
http://www.thinkwiki.org/wiki/Xorg_RandR_1.2#Output_port_names

that (at least) the intel and radeon drivers use different outputname values :)
