Old Acer laptop with SiS chipset

I'm trying to revive into semi-usable state an old Acer laptop my dad has, and I'm having trouble with the chipset. Specifically that the video is locked at 1024x768 and with all the distributions I've tried except sparky linux, I get horizontal artifacting in the display, and sound doesn't work outright. In my research it's seemed that no one's really touched these chipsets for many years, but I've confirmed via documentation that his chipset is supported under the sis-630 chipset driver, and I've found this https://www.kernel.org/doc/html/late...2c-sis630.html
But I don't know what to do with it. Any help please?
