Performance of 2D streams

In Brook+, 1D streams are limited to 8192 elements. To get past this limit, I will have to use 2D streams. As my data are however intrinsically 1D, there is some freedom in choosing the dimensions of the 2D stream. Are there any performance issues related to either memory access or parallelism related to stream dimensions? Is a 1*8192 stream equivalent to a 8192*1 or a 128*64 stream?
