Good point. When we get the data for the one case we know exists, we will have a
better idea if a special quirk for this case is feasible. Assuming that this is
not the only example of this hardware, then we might limit the breakage from
this patch. At least the random code would be needed and useful in keeping our
maintainer happy, which has a some merit.
