I would suspect the latter - these old VIA AGP implementations were notoriously
unstable and problematic even in Windows and it's not unlikely that different
BIOS versions may configure the card differently (AGP 2X/4X, AGP fast writes
on/off, etc.)

You can also try updating the motherboard BIOS and try playing with any
AGP-related BIOS settings to see if they change the situation.
