Applying this quirk to the 855GM in all systems causes regressions (Debian bugs #493096, #619019). Instead, apply the quirk to specific models as listed in the old X driver.
I don't see any explanation for this quirk being applied to the 845G, except perhaps that VT switching used to hang if pipe A was turned off. However, that seems to be a problem only when using UMS. So remove the quirk for the 845G as well.
