The BusID *MUST* be the same for both screens of a dualhead 
Radeon card.  Do NOT specify one as 1:00:0 and the other as 1:00:1

You also need to specify one as "Screen 0" and the other as 
"Screen 1".

XFree86 4.3.0 was released before the Radeon 9800 existed, so it 
does not support that card.  You need XFree86 CVS to use Radeon 
9800, or you need to fake the ChipID to hack around it with 
4.3.0.
