Jon Doane, to alleviate your pains, set radeon.dpm=0 as a boot option.
Crippling GPU performance is not a solution and doesn't alleviate pains because it basically forces me to not do anything 3d-related. I would rather boot with X disabled so I can force the perf level to high. This is what I used to do and it's not an acceptable solution.

I've literally been doing: "echo high > /sys/class/device/drm/card0/power_dpm_force_performance_level" every day to boot my machine for over a year
See comment 55 if your system is running systemd, you can use this service:

It will do it for you at startup, it's painless and I'm using it since 19 months without any issue.
This sounds a lot like what I've been doing manually which sounds nice. Thanks for the input. I honestly would like a solution that doesn't cause my machine to draw an additional 90 watts at idle though. As I said, I've been doing this for well over a year now and I'd prefer a solution, not a hack, considering how old this issue is.
