Thanks for the analysis.
In theory we could not fail DAC if the machine has <4GB RAM to work around such buggy drivers, but then they would fail anyways with >4GB. Also the failure was intended to allow some drivers to use more efficient non DAC operation.

The reason I blacklisted all was that there was a small triple of data corruption reports with VIA bridges. Also it's impossible to get any errata information out of VIA. And there are not that many >4GB VIA systems because these chipsets are usually used in lower end systems.
