Thank you for your help MrMazda.
I was finally able to get modesetting to load in the 5.4.0-58 kernel.

Device-1: AMD Barts PRO [Radeon HD 6850] driver: radeon v: kernel
Display: x11 server: X.Org 1.20.9 driver: loaded: modesetting
unloaded: vesa resolution: 1360x768~60Hz

Last night I tried the 5.8 kernel in the hopes to have mesa 4.5 loaded along with modesetting. The result was vesa only loaded with a poor resolution.

I look forward to trying out modesetting for a while. From what you've blogged about and other articles there seems to be an improved performance. Thanks for the guidance into a fascinating topic.
