We should probably consider to add a new flag for atac_cap in atac_softc
instead of defining WDC_NO_IDS. This flag could then either be set
depending on the controller type or requested by a device property.

But, for my specific problem I have refrained from doing this modification
now, because I found a better solution: on the MPC8241 I can configure
the VT6410 PCI interrupt as edge-triggered. That cures the problem
completely.

It needs to be checked if other architectures have the same problem with
the VT6410.
