Hi, I've got problems with a thinkpad (R51) with an Intel 855 chip as well.
To be more specific the part where I could select "Xinerama mode" is
grayed out in the Yast2 display section.
So I modified my /etc/X11/xorg.conf as I pasted it below and now have a
problem starting the adapter. I think I should enter some other value for
BusID "0:2:0" for the 2nd adapter. Who can help me out?
here the contents of the xorg.conf:
