I thought if it works with vesafb it should work with radeondrmfb too.
So do I, and as I said it does work for me. Also, the kernel radeon driver isn't actively involved in getting the pixels into the framebuffer, so I'm not sure how it could be responsible for the symptoms you're seeing but am rather leaning towards fbterm or freetype being the culprit.
