Mesa가 아주 오래된 GPU에서 하드웨어 가속에 대한 지원을 중단했습니까?

오늘 저는 S3 Savage IX-MV 비디오 칩이 장착된 HP OmniBook XE3에서 Kubuntu 12.04 LTS 부팅을 시도했고 다음을 발견했습니다:

로그를 보면 모든 것이 올바르게 초기화된 것 같습니다. 하지만 여전히 하드웨어 가속 대신 소프트웨어 렌더링이 있습니다. 물론 출시를 통해 glxgears소프트웨어 렌더링이 완료되었음을 확인했습니다. 즉, 전체 화면 모드에서 0.68FPS를 얻었습니다.

그래서 제 질문은 이 칩의 하드웨어 가속 지원이 Mesa에서 완전히 포기되었다는 것입니다. 아니면 어딘가에서 잘못 구성한 걸까요?
