Checking output before/after wpa_supplicant -Dwext on the installed
system, I saw ctr and ccm reference count changed. I've copied them
into d-i and after a few modprobes I managed to get networking with
the same commands as before:

  wpa_supplicant -i wlan0 -c wpa.conf &
  udhcpc -i wlan0

Ben, I guess it might make sense to add those to crypto-modules? Not
sure how feasible it would be to figure out which other ones might be
interesting for other wireless modules though…

→ I can open a bug against src:linux to keep track of it.

Ben mentioned on IRC: CONFIG_DEBUG_SYSLOG=y which might be helpful for
the udeb. Adding this option on top of sid's wpasupplicant-udeb isn't
sufficient, since one also needs adding the -s flag to netcfg's execlp
call. Once both udebs have been modified, wpasupplicant lines end up
in syslog, which is definitely helpful.

→ That should probably become 2 extra bug reports (src:wpa, src:netcfg).

Beware of the order: passing -s without CONFIG_DEBUG_SYSLOG=y means
getting an error and usage in syslog, so netcfg should only be patched
when wpa is ready.

Once we get there, it might make sense to pass (or make it possible to
pass) at least -d to wpa_supplicant.

→ An extra bug report for netcfg.
