Thanks!!! I compiled the patch in and now I can load radeonkms!
I sort of understand the patch; one main change seems to be the definition of acpi_get_table in sys/compat/linuxkpi/common/src/linux_acpi.c so now the symbol is found.
I had the module load error (before adding Jung's patch) on a fresh build done exactly following the instructions.

Please try this patch.

> Correct. It's almost certainly missing symbols. To find out what they are without crashing your system, load linuxkpi, then load drm, and *then* load radeon. Note that if your hardware is SI or newer it's supported by amdgpu.
