When trying to load the patched module ("insmod brcmsmac.ko"), I get:

insmod: error inserting 'brcmsmac.ko': -1 Invalid module format

And dmesg:

brcmsmac: disagrees about version of symbol module_layout

What I did? 

- Got the current kernel source¹ from Debian 
- Unpacked the files on the desktop
- Applied the patch to the file
- Run "make menuconfig" and followed this² instructions
- Run "make SUBDIRS=drivers/net/wireless/brcm80211/brcmsmac modules"

I must be making something wrong.

I know I could try with kernel >3.3-rc2 where the patch is already 
applied but my guess is that you prefer to check if the patch works 
with current kernel 3.2-9 because that's what wheezy will use, right?

Any help on how to bypass this will be appreciated.
