VIA S3 Savage - Internal error: could not map aperture range

Olá
Estou tentando usar o driver xserver-xorg-video-savage do Debian 9 em uma placa de vídeo integrada VIA ProSavageDDR P4M266.
Ao tentar iniciar, recebo:

(EE) Server terminated with error (1). 

Em /var/log/Xorg.0.log:

Se precisar, mando o log completo.
Sim, é um hardware jurássico, mas espero que, com o driver funcionando, tenha mais velocidade que usando o vesa.

Alguém? Ocorreu esse mesmo problema ai compilar o xf86-video-savage para o Arch Linux.
