AIUI, the Binary Blob for driving the GPU is 32 bit code,
so when using 64 bit Raspbian, does that mean that one
CPU core is configured as 32 bit to provide the video?
If so, how is communication arranged between the 64 bit
and 32 bit CPU cores?

Oh, I just realised that you were mistaken about what the GPU
binary actually runs on - it's the software that runs on the GPU,
it doesn't (and can't) run on any CPU core. The software on the CPU
is drivers that talk to the proprietary software on the GPU, which
as described in my last post are fine to be 64bit programs, and
the Linux ones are also open-source.
