It would be great if there's some knob we can turn in the controller
PCI config space but I really have no idea whatsoever.  :-(

I wonder if enabling EDAC PCI parity error detection would show up these
problems - either on the controller itself, or its upstream PCI bridge chip?

modprobe edac_core check_pci_errors=1

alternatively, "setpci -s<slot>  STATUS" should also show status
register bit 15 having been asserted, I think, and lspci -vv should say
"<PERR+"

It's something to check, yes. It would be somewhat surprising if that 
were occurring - detected PCI parity errors should cause a target abort 
and cause a transfer failure, not silent data corruption. But again, on 
an old VIA chipset, for this to be handled improperly wouldn't be 
shocking :-)
