The server still supports it, we just had to remove support in the
radeon driver as that code was stopping forward progress, I started
some work to reimplement old-style dual-head on top of the randr code,
but unless RH have a pushing reason (read pissed off customer) I doubt
I'll be putting too much effort into it,

You can see what i've done so far

it doesn't work but you can see where I was going...
