OF configures devices at startup time, not when you open them. (If you
browse the device tree in OF before booting, you'll see that all of
the addresses and interrupts have already been assigned.)

(Oh, and bm is a built-in device attached to obio, not a PCI card.)

I'm not convinced. Linux and Darwin don't have this problem (I think?
Can anyone confirm?) I suspect we're doing something wrong somewhere
(failing to set some grackle-specific status bit or something) which
is causing these problems.
