Anyone had any success getting CMake to construct x64 OSG build
targets in one of the 64bit flavors of Windows? I'm using Vista64 but
I'd imagine XP64 is the same. We have a developer investigating this
but I thought I'd ping the list to see if anyone else is doing this.

I couldn't tell from reading your post - but if you're not compiling
the OSG yourself (IE...running a binary distribution), grab one of the
developer snapshots and compile that.
