I have a huge update for you all. After many hours of reverse engineering, I was able to SUCCESSFULLY PATCH that SeriTek 1S2 ROM for the SIl3112 cards, allowing it to work with ANY 512K EEPROM! It functions just as it would with a "supported" EEPROM, working with and booting both OS X and OS9! The patched ROM image is attached. Please test, and let me know how it works!
