Ok, just took a look at it. Sadly I've to say that I don't think that we can 
distribute this kernel module under the given license. :( So I've to close this 
bugreport with "won't fix". If anyone is aware of a possible solution please 
let me know, thanks!

Thanks for your time, Marcel. This bugreport will help users with the according 
hardware to get this driver working by following the described steps.

Hi,

wifi device

  Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g
  [14e4:4315] (rev 01)

as found in Lenovo Ideapad S10e isn't supported by neighter
b43 nor bcm43xx kernel module.

Using linux STA drivers from Broadcom

  http://www.broadcom.com/support/802.11/linux_sta.php

one can compile a module named

  wl.ko

which just works fine.

Install instructions for 32bit:

  http://jomcode.com/fadhil/?p=59

  apt-get update
  apt-get install linux-headers-$(uname -r)

  wget -qO-
  http://www.broadcom.com/docs/linux_sta/hybrid-portsrc-x86-32_5_10_27_11.tar.gz
  | tar xz make -C /usr/src/linux-headers-$(uname -r) M=$(pwd)

  rmmod bcm43xx ; rmmod b43 ; rmmod b43legacy ; modprobe
  ieee80211_crypt_tkip ; insmod ./wl.ko

Voila.

Thanks mika for your patience at #grml :)

Greetings,
Marcel.
