Sweet! Did you consider using AutoGEMM.py from clBLAS instead of a static GEMM kernel ?
I was considering using a polyhedral compiler macro (like PPCG), for writing OpenCL kernels in matlisp, but it's not clear how optimal this would be.

On top of it, this approach gives better performance in most cases even on AMD, and especially on Nvidia. Now, I have AMD hardware, but it is better to create an overall more encompassing library, thus I avoided clBLAS :)
When I need to write my own OpenCL kernels, I use ClojureCL - it gives me easy management while still retaining full control of the kernels and their performance.
If you want to take a look at it, the AutoGemm generator seems to be a simple python script written in order to overcome the limitations of the C preprocessor. I was considering using its tiling structure, since I already have a Lisp->OpenCL compiler in place (and have had no luck beating it). See, for instance,
