2.4 has code in the pci quirks to disable the register which makes the chip masquerade as a VP3, and forces it to identify itself as an MVP3 part. I'm curious whether this has an interaction here.
This doesn't do anything but change the ID so that Linux drivers are not confused anymore. This caused a lot of trouble in 2.2, especially with the old VIA IDE driver.

Fortunately all these chips use PIIX-compatible extensions to the PCI bus, so they are all interchangeable to some degree.

I'm curious if all of the other boards in Alans bug reports also fall into the stranger category.
It's possible. I have a board (VA-503A), which has a masqueraded 598, which identifies itself as 597, and a 686a southbridge. This got the 2.2 ide driver completely confused, for example.
Maybe the VIA IDE chipset support option should depend on PCI quirks now ?

No, in 2.4 the VIA IDE driver doesn't use this (northbridge) information anymore.
