I used a matrox g400dh before i upgraded my system to an amd64 one. Now
I'm using an ati radeon 9250 card and having trouble getting xinerama
working like it worked before. with all the special CRT2-Option I'm able
to get a streched screen but no center hints and so on are given to my
application which means resizing, maximizing, centering and so on doesn't
work really good. I'm getting the following "warning" on loading xorg.

(II) Primary Device is: PCI 01:00:0
(WW) RADEON: No matching Device section for instance (BusID PCI:1:0:1)
(--) Chipset ATI Radeon 9200PRO 5960 (AGP) found

since I have a PCI:1:0:1 device section in my xorg.conf I guess the error
is here:

drm0 at pci1:0:0:  class=0x030000 card=0x004e1043 chip=0x59601002 rev=0x01
    vendor   = 'ATI Technologies Inc.'
    device   = 'Radeon 9200 Pro (RV280)'
    class    = display
    subclass = VGA
none3 at pci1:0:1: class=0x038000 card=0x004f1043 chip=0x59401002 rev=0x01
    vendor   = 'ATI Technologies Inc.'
    device   = 'Radeon 9200 Pro (RV280) - Secondary'
    class    = display

is it possible to attach drm1 on none3?

Part of my xorg.conf

Section "Device"
    Identifier  "ATI1"
    Driver      "radeon"
    #VideoRam    16384
    BusID       "PCI:1:0:0"
    Screen      0
    Option "CRT2Position" "RightOf"
    Option "CRT2HSync" "30.0-70.0"
    Option "CRT2VRefresh" "50.0-120.0"
    Option "MetaModes" "1152x864-1152x864"
    Option "MonitorLayout" "CRT,CRT"
    Option "MergedFB" "true"
    Option "NoMergedXinerama" "false"
#    Option "MergedXineramaCRT2IsScreen0" "1"
    # Insert Clocks lines here if appropriate

Section "Device"
    Identifier  "ATI2"
    Driver      "radeon"
    BusID       "PCI:1:0:1"
    Screen      1

All the ATI1-Options where added only for radeon since w/o them I'm only
getting a "copy" on my 2nd monitor.
