Ok got one now:

https://www.cs.tcd.ie/~furlongm/iwlwifi/minicom-wpa_supplicant-output

Reloaded the module halfway through to see if that made any difference.
Sometimes it sees some of the access points after rmmod-ing and
modprobe-ing it (never sees as many as the ipw driver though), but this
time it didn't make any difference.
