I just chanced across a site last updated in 1999 that covers my Shuttle HOT-569 board in excruciating detail, and ONLY that motherboard. It outlined the issue I was having with Win95 not recognizing stuff in the chipset, and provided the filename for Shuttle's patch to fix it in Win95. I then used THAT to find Shuttle's European site for downloads, from 2004, and made a backup copy of everything on it, including the patch I needed. Unless Win98's CD can be used as a source for drivers in Win95. It's been forever since I messed with that stuff.
For the record, these are the pages. God knows how much I hate finding forum posts from ages ago, with people never even leaving breadcrumbs for future researchers. "lol i'l pm u the fix" and "n/m i fixed it"....
The site containing the guide for the board: http://www.pchardwarelinks.com/main.htm
Shuttle's file archive: https://download.shuttle.eu/Archive_2004/Utilities/
It's possible there might be a similar solution for your video card woes, but that may be like tracking a unicorn through Brigadoon. I'm sure you've already tried, but I would search various IDs on the card, its retail name, and have whatever search site you use, perhaps limit the searches to archive.org to find old pages that may have the driver packs, or at least more filenames to go off of.
