I'm sorry I don't know. The chipset environment for the same basic

Normally the radeon driver is able to self detect the connected
channels correctly... well not in that case

Hmm, something like this should work

	MergedFB      yes
	CRT2HSync     ...
	CRT2VRefresh  ...
	IgnoreEDID    yes
	MetaModes     1680x1050-1024*768
	CRT2Position  Clone
