I've actually already run into that to some degree, because my
frontend is 32 bit and nVIdia has dropped support for that past the
version 390 drivers.

I think that the Linux AMD issues predate the newer AMDGPU stuff in
the kernel entirely. Note that I use Gentoo for everything, so the
kernel and any AMD related drivers are pretty current. Like I said,
VDPAU (albeit not in MythTV) seems to be working great on this
machine.
