How high can I push Xinerama with the GMA X3100? I'm planning on buying a 1920x1200 Latitude D830 and hook up (at least) a 1600x1200 20" lcd to it then use them with Xinerama. Do I have a chance with that? How about 1920x1200 on the external graphics port?

And how about AIGLX? Probably won't work with more than one because of 2048*2048 texture limits, right?
