Problemas com um laptop Positivo Z94

[megaloco]

Sou novo na área, e instalei neste notebook, o sistema UBUNTU 8.10, só que não estou tendo resolução de vídeo, camera integrada e microfone.
As especificações deste notebook são essas:
# Intel Core2Duo T5750 (2GHz, FSB 667MHz, 2MB Cache L2)
# 3GB de memória RAM
# disco de 250GB
# leitor de cartões
# chipset SiS 671
# vídeo SiS Mirage 3
# rede sem fio Realtek 8178B
# rede com fio SiS 191
# webcam de 1,3 megapixels
# tela de 14,1″ capaz de fazer 1280×800 (widescreen)

Porém, consegui ligar a net nele via Wireless, mas no restante, estou levando uma surra.
Se alguém puder me auxiliar, ficarei muito grato

Abraços à Comunidade (e espero algum dia estar à altura da mesma)
