They are using software to work around the hardware's limitations. That
software is not written for nouveau.

For GF100+ GPUs, yes. NV67 is a fair bit older.

Each hardware generation supports what it supports. For NV67, which is
effectively a NV4x, that's basically the DX9 feature set.
ARB_framebuffer_object is, in essence, a DX10 feature, but NVIDIA was able to
provide the software fallbacks for the cases in the ext that aren't handled,
and fast-path the cases that are. Nouveau hasn't done this. Patches welcome.
