Both machines boot (and do wireless) correctly with your NETDEV_PRE_INIT hunk placed just after the ndo_init block, instead of just before where you placed it. That's i386 kernels on both. But curiouser and curiouser... the laptop can do 64-bit, so I built my 64-bit kernel, and went through the motions to reproduce the early boot crash with the patch as you had it: but the x86_64 kernel boots (and does wireless) correctly with the NETDEV_PRE_INIT hunk just where you placed it, before the ndo_init block. Perhaps there's a difference in the 32- and 64-bit startup sequence with respect to notifiers; or perhaps your change tickles another bug. I don't know, I'm turning off now.
