Using the 3.7 kernel almost all these modules are loaded save the 
iwlegacy which I load after booting (not sure how to configure the
system that it loads this module, but only if the 3.7 kernel is booted)

lsmod | grep iw
iwlegacy               55193  0
iwldvm                130343  0
mac80211              462917  2 iwlegacy,iwldvm
iwlwifi                76446  1 iwldvm
cfg80211              149752  4 iwlegacy,iwldvm,mac80211,iwlwifi
led_class               3098  3 iwlegacy,thinkpaacpi,iwldvm

The issue is now ifconfig gives:

pan0      Link encap:Ethernet  HWaddr 76:71:80:c4:62:9b  
          inet6 addr: fe80::7471:80ff:fec4:629b/64 Scope:Link

          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

This is almost the same result I obtain when using the older 2.6
kernels, save the pan0 interface. I have no idea what this is supposed
to be.

In any case wicd nor knetworkmanager find the card so I cannot connect
comfortably to a wifi red.
