The C++0x standard has formally incorporated the new memory model
and atomic operations into the current working draft for the standard:
http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2008/n2521.pdf
As this standard has not been approved, it may change, but significant
changes are unlikely.
I think gcc would be better served by implementing the standard than
by trying to define a different model, both because getting such models
right is hard and because multiple models make life hard for the
programmers that must code to multiple platforms.
