Thanks for the feedback Brian!
It's not a lot of work, but it is additional choice confusion when
trying to find the correct AMI. However, I do suspect that anyone with a
Reserved Instance over a longer period (3 years) for an instance type
that is PVM may want this, so lets perhaps continue AMD64 PVM EBS-backed
then. And if we can't get HVM S3 backed, then PVM S3 backed?

Sadly, I haven't had time... but volunteers welcome!! Yes, Apache
software license, so is DFSG compatible.

Indeed; its inconvenient to install from nvidia-kernel-dkms as it
depends on (a) installing compilers, (b) network access to fetch source,
and (c) spending time compiling! However, another option I haven't yet
tested - nouveau.
