Hello,
I don't know if this will help, and i am kind of a linux/SME newbie, but i got the drivers compiled for this FastTrak card.
I've done this a few months ago, so i can't really tell you how exactly i've done it. I downloaded the dev-tools (SME6.0) for compiling your own drivers and got the source-files from the promise site. Reading al the manuals.... lots of problems and sweat, but got things working finally....
I don't know if it wil work (like is said: i'm new to Linux/SME) but i can send you the .o -driver file.
