placa trident tgui9440 + mandrake 9.2

ola a todos

tenho uma placa de video trident tgui9440 e mandrake 9.2
mas o xfree nao consegue iniciar, tentei mudar o drive da placa
no arquivo /etc/X11/XFree86Config-4 para usar um drive vesa, mas
mesmo assim ele continua sem iniciar. o inittab esta configuado para entrar em modo grafico. o que mais pode ser feito para poder corrigir o problema?

falows

tenho esta placa configurada e funcionando no slackware :)
00:0a.0 VGA compatible controller: Trident Microsystems TGUI 9440 (rev e3)
Ai vai o meu XF86Config, talvez lhe ajude
