Multiseat with Nvidia and X11R6.9

Hello!

I'm configuring a multiseat system, using two Nvidia cards under 6.9.
The two seats works fine, but not together: I can't have both active at the same time.
Since to post more than 40 kb of configuration and logs seems excessive,
all my configurations can be seen here:

Thanks in advance for the help.
