dual headed opengl

[jahshaka]

I am running redhat 7.1 on a sgi 330 system using a nvidia geforce2 card and am trying to set up Xinerama for dual headed support, with a second geforce2 card but have read that the nvidia drivers wont do hardware opengl with this setup

Anyone trying to do this or who has a working dual headed opengl accelerated system, please help me out!
