I don't know because on my boxen I had the framebuffer modules built in the 
kernel.  Therefore I had to recompile the kernel with all the KMS settings as 
suggested in the article above and remove the framebuffer modules completely.

I think that the solution is probably to go for the full KMS approach and 
remove the framebuffer modules as already suggested.  Then come back if it 
doesn't work.

The xorg-server-1.8 migration is necessary if you need to configure particular 
devices.  HAL and its fdi files are no longer used.  In absence of any other 
configuration files under /etc/X11/*, xorg will use the files in 
/usr/share/X11/xorg.conf.d/* which may or may not agree with your hardware.  
That's what the xorg-server-1.8 migration URL is for.
