I don't think there is a hard line.

Between radeonkms and amdgpu =97 we know, radeonkms supports the first=20
two Graphics Core Next architectures and everything *before*, while=20
amdgpu supports the first two Graphics Core Next architectures and=20
everything *after*.

Between the "modern" radeonkms (LinuxKPI-based) and "legacy" radeonkms=20
(old direct port to FreeBSD base)=85 well, "if you have problems with=20
modern, try legacy". I guess we could eventually collect enough reports=20
to know which GPUs only work on legacy. But no hard line.
