No. That's not a fair workaround. There's too many other cases that
this would break. Amrs are farily rare, and having a workaround that
negatively affects other hardware is undesirable.
The problem is that the AMR device attaches to only one of the PCI
devices, when it should attach a dummy driver to the second one. This
is due to flaws in the amr hardware design, which we've also seen in
the aac cards.
