Shouldn't Xinerma be handling that. If it doesn't then as usual XFree86 is
broken. 

As for multiple access issues this is a huge topic. I plan to hold off until 
2.5.X and when I start working on the framebuffer filesystem. Here we can
have multiple files where each on can represent a specific type of 
functionality. With this we can control which functionality can be used
by only one process at a time versus functionality that can be managed
between multiple process.
