So, putting my laptop installation aside, and concentrating on a VM
using KVM with USB pass-through to a USB adapter (USB ID is 0bda:8176,
that's RTL8188CUS), I've been able to verify (assuming firmwares have
been made available every time):
 - wheezy amd64 works with WPA (TKIP) and WPA2 (AES)
   [ sharing network over a Firefox OS phone with those denominations. ]
 - wheezy amd64 works with WPA2-PSK/AES
   [ as advertised by my home router ]
 - sid amd64 doesn't work with any of those, even if I build an image
   with wheezy's netcfg and/or wheezy's wpasupplicant-udeb.

I've also verified that installing over a wired connection lets me
configure wpa_supplicant and connect to wireless from within the same
VM, so there's definitely something fishy within d-i, even if I don't
know what yet.

Anyway, that doesn't allow me to conclude on the “WEP might be OK”
topic, but various WPA setups are clearly broken. Let's see whether I
can get that debugged further tomorrow.

Mraw,
