Yes. I'm running a similar setup, using TwinView with its Xinerama
extentions enabled. And wmsetbg works perfectly here.

When i use a Background smaller than 2560x1024 it gets tiled. (Wich is
perfectly normal, since i use the option -t by default.)

And when it comes to window and appicon placment, i didn' run in any
problems yet. (The appicons are placed in the correct screen.)

Ok.. I guess i'll post the intresting parts of my xorg.conf. Mayby it'll
help.

Section "ServerFlags"
EndSection

Section "Device"
    Identifier  "GeForce"
    Driver      "nvidia"
    Option      "NoLogo" "true"
    Option 	"TwinView"
    Option 	"SecondMonitorHorizSync"     "31.5-96"
    Option 	"SecondMonitorVertRefresh"   "50-160"
    Option 	"MetaModes"                  "1280x1024,1280x1024;
1024x768,null; 800x600,null; 640x480,null"
    Option      "ConnectedMonitor"         "crt,crt"
EndSection


Section "ServerLayout"
    Identifier  "Simple Layout"
    Screen "Screen 1"
    InputDevice "Mouse1" "CorePointer"
    InputDevice "Keyboard1" "CoreKeyboard"
EndSection


And just remember to compile WindowMaker with Xinerama support.
