Assuming you have both adapters working but coming up as separate 
displays, you may just need to enable Xinerama to combine them:

Section "ServerFlags"
        Option       "Xinerama" "1"
EndSection

If that's not what you're after then you may need to specify more details. 
Also consider posting to -questions rather than -x11 as the former has a 
wider readership and is probably more appropriate for general howto 
questions.
