we are facing problem in getting 6 displays from ATI FirePro v9800 card(6 display output card) on RHEL 5.4 kernel ver. 2.6.18-164.el5. we are currently getting 2 displays only. can you please suggest us in solving the problem.
Going from memory here but I think the issue is that the RandR support in X on 5.x is too old for Eyefinity to work, ie it's an X thing not a kernel thing.
