Might be even nicer if there was a version bit that could be checked
to see if the feature is present
rather than hardcode the version number into the driver....

Yep - it does!
 Didn't even realise there was firmware involved! - google searching
showed on Debian (I'm running bookworm) there is the package
firmware-non-free
  https://tracker.debian.org/pkg/firmware-nonfree which generates the
binary package firmware-amd-graphics
  which has several releases (See
https://packages.debian.org/search?keywords=firmware-amd-graphics)
and there is a newer one 20240709-1 which I installed (lots of new
files in /lib/firmware/amdgpu) then rebuilt my kernel with latest
mainline:
...
commit 0108b7be2a18 (HEAD -> master, mainline/master)

....

Yep - it boots beautifully !

Not sure what firmware file it ends up loading :
