Seems VIA have uploaded new Hyperion 4in1 drivers version 4.49p to their FTP Server! No word on what's new.

VIA Hyperion drivers are suitable for any VIA chipset and all Microsoft Windows Operating Systems. Hyperion driver sets include INF, AGP, IDE and IRQ related drivers.

Update: I'll add more Mirrors as I find them. Download VIA Hyperion 4in1 v4.49p
