I just got an 8500 working dualhead yesterday - either MergedFB or
Xinerama,

With MergedFB you don't use the X Screen stuff, it is in the driver, X
6.8.0 and beyond support this... it also allows dualhead 3D to work..

the other config actually just provides two heads - separate screens, DRI
doesn't work.....

Also the second PCI ID on all graphics cards at the moment is a windows
thing, MS made a mess of their device model in W2K with respect to
graphics cards they have one PCIid one head relationship (e.g. Win98 used
to be able to do dualhead on my mach64 laptop, W2K cannot...) so vendors
added a second fake PCIid... currently Linux/X should always used the
primary ID and ignore the secondary...

Dave.
