First, I can't believe that radeonkms does anything, unless you have an older discrete GPU in your machine. In your case it's falling back to VESA according to Xorg log. Vega is still experimental as of 4.16. According to various online sources, it seems like we have to wait for 4.18 until Vega can be considered stable (meaning we won't spend time trying to fix bugs that are not obviously a FreeBSD problem). I think we can reach 4.18 before the end of this year. Until then, your best option is probably booting with UEFI if you can and using the scfb driver. It's much nicer than VESA...
