So, I compiled the Broadcom proprietary driver (wl) against an old
2.6.32-rc5 that I still had.
The compilation went fine so I guess I don't need the patch after all :
r...@mini hybrid-broadcom # make
KBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd`
make[1]: Entering directory `/usr/src/linux-2.6.32-rc5-homemade'

/usr/local/hybrid-broadcom/wl.o
see include/linux/module.h for more information
make[1]: Leaving directory `/usr/src/linux-2.6.32-rc5-homemade'
..the module is copied at the right place and depmoded :
r...@mini hybrid-broadcom # cp wl.ko
/lib/modules/2.6.32-rc5-homemade/kernel/drivers/net/wireless/
r...@mini hybrid-broadcom # depmod -ae

r...@mini ~ # uname -a

All others b43 drivers are blacklisted and does not load at boot :
r...@mini ~ # lsmod

wmi 4083 0
i2c_i801 7106 0
sky2 39059 0
evdev 6653 14
(Yes, very few modules, I like my kernel free of useless stuff).
Now we load wl (depmod and everything was done, the build went
correctly, I will probably output if needed) :
r...@mini ~ # modprobe wl
Lsmod shown the drivers is not in use :
r...@mini ~ # lsmod
Module Size Used by
wl 1262065 0
ipv6 225039 18
wmi 4083 0
i2c_i801 7106 0
sky2 39059 0
evdev 6653 14
Not much in dmesg either :
r...@mini ~ # dmesg | tail -5

As you can see, it does not :

Conclusion :
The Broadcom proprietary driver (wl) FAILS to detect the card.
Feel free to point me any errors I could have made... I could try with
the 2.6.32-rc* patch if you'd like but the compilation went fine (no
error no warning).
