Ooh, it also occurs to me that we could change the construction of
the device name instead of overloading 's#' to remove the confusion.
So for a native GPT we could call it 's0.<index>' instead of 's<index>'.
Or perhaps we could just call it 'g<index'> instead of 's<index>', so
something like: ad4g0, ad4g1, ad4g2, ad4g3.
Just throwing out ideas.
