No. It's not possible, at least not at this point. The decision of allocating the DART space or not (and thus eventually stripping the max available memory) is done very early. So early that the kernel isn't yet running at it's link location ;) So the kind of code we can actually run at this point is limited, with various tweaks to deal with the relocation issue.
It's not very pretty, I hope we can improve that later, but that is not something that will happen in the upcoming weeks .
Ben.
