Using Dual head card with framebuffer

[Claude F. <cf...@gm...>]

Hello to everyone,

     For quite a while now, I have been trying to get an ATI Radeon  
7000 Dual headed to work with XFree86 4.3.0. What I'd like to do is  
the following:

A) Put more than one card in the system (3 in fact... 2 PCI and 1  
AGP) Have each head of the cards to work independently
Example:    Card #1 --> head #1 = /dev/fb0, head #2 = /dev/fb1
                      Card #2 --> head #1 = /dev/fb2, head #2 = /dev/fb3
                      Card #3 --> head #1 = /dev/fb4, head #2 = /dev/fb5

Is this possible with radeon or NVidia Card? I know it is with Matrox  
G400 & G450

B) Have multiple X server to run independently and simultaneously  on  
each cards head (I was able to do this with 6 cards with PCI address  
method ex: 1:0:0 but not with frame buffer on dual head)

So far, FrameBuffer is working on only one card, and one head...  
really basic.

My questions.

1) Is this the correct place to ask this question? If not what are  
other resources or website.

2) If you know how to achieve my task in section A, help me please...


What I have found so far on radeonfb is VERY old documentation  
(2002)... I need more recent stuff.


Thanks to everyone...
