Actually, I spoke to soon about the problem having been fixed in Edgy. It seems I can get my dualhead working, but only by installing Ray's package (from his post directly above my last post) then attempting to restart X (which fails but allows my ATI card to initialise its BIOS), then re-upgrading to the Edgy xserver-xorg-core package. So I guess the folks looking after Debian Unstable haven't fixed this yet either...
