Yes, we have tried this solution, but we have not been able to get this
patch to work with other framebuffer drivers than Matrox (Matrox seems
to be a very "nice" driver). The problem occurred when we needed support
for more than one card/manufacturer (eg. Nvidia, ATI, Matrox, sis). Our
main environment are 4 ATI cards with 8 output on each card ( A total of
32 outputs from one PC - each with its own mouse and keyboard ), and the
solution from Miguel Freitas did not work in our environment.

I will look into this once again, but I know we had some problems with
only one X-session showing at the time (and the rest went blank or
"sleeping") when we used the patch from Freitas.

We have also tried the backstreet ruby solution, but this was not
supporting the kernel version that we needed at the time when we tried
it. Maybe it will work now ? (Kernel 2.4.21-pre5 or later)
