X and screen finding

[r j <raphigolart@raphisme.ch>]

hi,

i installed more or less a woody on a digital venturis fx 5133 ( year 
1996), s3 trio graphics.

when i launch X, i get this : (EE) no devices detected
									fatal server error
									no screens found


i'm new to gnu/linux...i read as much as i can to understand how it 
works, but i come from the mac world...


if anybody knows what ( and where) i have to tune my system so that i 
can have at least a desktop displayed, it 'd be very apreciated

thanks
