The fs register looks quite wrong to me.
It probably crashes then in process_attach when accessing
NtCurrentTeb->xxx(which uses the fs register).
So I would *guess* the fglrx driver wants to use this register for its own
purpose(for whatever reasons), which simply doesn't work with wine.
You could probably verify that with a simple test prog, which dlopens libGL and
checks the fs register before and after loading GL.
But reading comment #6 the option UseFastTLS="2" should work around that
problem, so I dunno if it worth to put too much effort into this ;)
