Thank you very much for the info and the link.
I tried almost all permutations and combinations of driver options but I did
not get the dual monitor to work. Meaning I got video on both monitors but
it is the same view (no spanning). 
these are the options I tried:
"OpenGLOverlay" "off"
 "Mode1"  "1280x1024"
 "Mode2"  "1280x1024"
"DesktopSetup" "LVDS,AUTO"
"HSync2" "65"
"VRefresh2" "60"
"VideoOverlay"  "on"

One question: what exactly do you mean by "I use "Splitview" on the server
side..."

Maybe I should just get an nVidia card...
