That wont happen because:

1) Not all video hardware and drivers support having multiple X 
   server instances running on them.

2) For those drivers that do actually allow multiple X server 
   instances, DRI will only work on the first instance as it does 
   not support multiple X servers running on one card all 3D 
   enabled.  The Radeon driver in CVS has experimental support to 
   do this however.

3) The number of problems that do arise when using multiple X 
   servers on a single card are quite high, and rather complex to 
   debug/troubleshoot.  This would place a large support burden 
   on Red Hat for something that XFree86 supports only in a 
   highly experimental "if it works for you, great" manner.


Users are free to customize their setups to run multiple X 
servers if they wish, but Red Hat will only support a single X 
server running on one video card at a time.  People who run 
multiple servers and have crashes/problems are free to submit 
patches to fix the problems in bugzilla though.  ;o)

Hope this helps.
