When we detect the problem, we are too far past the initialization to switch
from DMA to PIO.

We certainly hope to fix the issue. We do know that the failure occurs when b43
is loaded after a cold boot, but if one warm boots after using wl, then it works
OK. There is some kind of initialization problem that only shows on Atom and
some Intel Core Duo CPUs.
