Hello,
I have forward ported the hacky patch I sent earlier to the linux-omap mailing
list. This patch applies on top of 2.6.37-rc1 and is working fine for me.
Unfortunately, I still haven't had the time to work on the real solution for
it. As stated earlier, this patch assumes that you have a wl1271 expansion
board and not something else.
Give it a try if you dare! 
From my side, this patch comes with absolutely no
warranty and should only be used as an example or for trying things out.
If you have any questions or need any help, just let me know.
Cheers,
Luca.
