Ah sorry about that! This should work:

template<size_tMax,size_tMin>

struct  my_linear  :  bgi::linear<Max,  Min>  {};

namespace  boost  {  namespace  geometry  {  namespace  index  {  namespace  detail  {  namespace  rtree  {

template  <size_t  MaxElements,  size_t  MinElements>

struct  options_type<  my_linear<MaxElements,  MinElements>  >

{

     typedef  options<

         my_linear<MaxElements,  MinElements>,

         insert_default_tag,

         choose_by_content_diff_tag,

         split_default_tag,

         linear_tag,

         node_s_mem_static_tag

     >  type;

};

}}}}}

/*...*/

typedefmy_linear<32,8>params_t;
/*...*/
typedefbgi::rtree<rtree_value_type,params_t,indexable_t,equal_to_t,rtree_allocator_t>rtree_t;

So this slightly more complicated but also more flexible since you may 
define Max/Min in the place where the rtree is created.
But it probably should also be possible to use the tag-based approach. 
I'll think about it and maybe prepare a patch...

I'm glad it's ok.
