I just unboxed a lenovo T431s and installed ubuntu 12.04.2. Everything went smoothly, but the wireless never came up. I'm pulling a a dhcp properly with NM on my wired connection, but ifconfig doesn't even show wlan0 at all.
I poked around the web a bit and eventually downloaded the linux firmware from the intel website, but checking the md5sum with the file already in /lib/firmware they match.
I'm happy to post the output of other commands if they'll help, but lspci and lshw are below.

The commands run were:

jth@t431s:~$ lsmod >> justin.txt
jth@t431s:~$ cat /var/log/syslog | grep iwl >> justin.txt1 Answer
For posterity:
The issue was not with the kernel and instead with the iwlwifi driver. A custom patch provided by one of the ubuntu kernel contributors fixed the problem and will be included in a patch eventually...
I stuck it up on my dropbox for the time being here
install with
dpkg -i wireless-iwlwifi-precise-dkms_3.6precise1sutton5_all.deb
