No, that doesn't work for me.  I need classic dualhead with separate
$DISPLAY so that I have separate virtual desktop switching on each.

I have seen that this works fine for the same Xorg version on other
computers not using the Radeon/ATI driver.

So I reported it to the ATI driver list (assuming my subscription went
