Yes. Open source radeon supports FBOs even with older hw (r100 and
r200 that are only GL1.3/1.5 hardware). But FBO support is missing
depth textures because of no texture format for depth buffer in the
old hw.

And I see that error when testing 3DMark2001SE lobby demo. It used to
render correctly but now it fails to render characters.
I don't know if incorrect rendering is caused by the error message.
