My comments.

To start two separate screens for _one_ user no needs for kernel or
xf86 pathces!
Instead use standard xf86 where XF86Config file contains "ServerLayout"
with two screens. Do not use xinerama.
To start programs on first screen use parameter -display
xterm -display :0.0
To start programs on second screen
xterm -display :0.1

set up Your xf86 starting scripts according this.

That all.
