Though, it may be interesting to understand why "traditional" dual-head 
doesn't work anymore with radeons.

I have a 9200 which also seem to only be able to use mergedfb with 
X.Org, and I've one report of a OpenBSD user who was using traditional 
multi-head on XFree86 4.4 with a radeon 7000, but cannot get it working 
with X.Org 6.8.1.
