Comment 13 for bug 56421

Matthew, there are a couple of possible paths. For maximum risk avoidance, wait for the new ipw3945 to be include in Edgy; if you feel like living on the Edge, upgrade your kernel outside of the normal channels (refer to bug #63418 for more information on both cases).

I lean toward the "wait" path, myself, if the system is otherwise stable and working (and the lack of ipw3945 after suspend isn't a show stopper).
