Very interesting.  What userland are you running?  I take it, the root
filesystem is mounted and system boot except for that interface not
coming up, right?

Your card is normally handled by what, iwlwifi?  What happens upon
modprobe iwlwifi (or whatever module you see loaded on the normal
boot)?  Another interesting question is whether it manages to load
the firmware...  What happens if you boot with debug in kernel command
line, with working and with non-working kernels resp.?
