I think "nonsense" is perhaps a little strong, Johannes, considering the
gist of my post was right. My memory failed me on the two points you
identified in your post: acceleration for older video cards was
introduced with 10.1.5 (not 10.1.4), and 3D OpenGL is still not
accelerated. However, 2D drawing and QuickTime *are* accelerated, and
everything else I wrote is correct.
From the 10.1.5 release notes:

Not a bad compromise, since the Rage II and Rage Pro are effectively
useless for 3D OpenGL even in OS 9. (They are a little better when
using RAVE, ATI's proprietary 3D API, but RAVE was abandoned by ATI long
ago.) What is it that you require OpenGL for?
