I posted this patch more for feedback and interest with minimal expectations that it would make it upstream. This patch will always be in our supported branches, but I will defer to everyone else on its worth for upstream.

How do they actually make their choices? Is it just about advertising 
dsp vs. dspr2 to user-space?

Have you looked into modifying the ELF platform via set_elf_platform() 
to help these binaries with identify the underlying platform/kernel?
