Running two X servers in this configuration will probably not work. The
two heads of the card share some resources and I'm not sure if the X
servers will be able to cooperate on those.
I don't understand why just running one X server in multi head mode with
Xinerama disabled doesn't do what you want. In this mode you get two
screens :0.0 and :0.1. Windows are explicitely attached to one of the
screens and cannot be moved to the other screen without magic.
This mode should work with the radeon 9250 (I'm using a radeon 9200 is
this configuration): just set up 2 device sections for the 2 pci devices
that show up (1:0:0 and 1:0:1) and 2 screen sections. See the radeon(4)
manual page for configuration details.
