I don't think there is a hard line.

Between radeonkms and amdgpu — we know, radeonkms supports the first 
two Graphics Core Next architectures and everything *before*, while 
amdgpu supports the first two Graphics Core Next architectures and 
everything *after*.

Between the "modern" radeonkms (LinuxKPI-based) and "legacy" radeonkms 
(old direct port to FreeBSD base)… well, "if you have problems with 
modern, try legacy". I guess we could eventually collect enough reports 
to know which GPUs only work on legacy. But no hard line.
