What I want is to get iw and nl80211 working properly so I can use 
netlink sockets to get all the information. Currently I cannot do 
anything as every iw command reports operation not supported.

If I compile the kernel withouth the wireless modules then they are not 
going to be recognized and compat-wireless will complain that .config 
that kernel was compiled without wireless.

On the other hand, what do you mean by replacing the wireless modules? 
just cut and paste from compat-wireless.

The issue is that 2.6.28 has nl80211, cfg80211 and mac80211 on their 
very stages. I think what will solve my problem is just updating those 
modules, but for that I have to change also the driver.

Besides that, the main problemm, as some guys pointed in the IRC 
channel, is that wl1251 driver is spi and they need something about the 
board interfaces.

Yes I'm aware of that. I have compiled the kernel and try to load it on 
the n900 with maemo rootfs and ... crashes.

Actually I have meego (mmc rootfs) also running on my N900 and wireless 
drivers work perfect. The problem is that the gui and develepment SDK 
and toolchains are still underdevelopment and I cannot then use 
something like the maemo scratchbox.

I have compiled an small application directly on the n900 with meego, 
but for larger applications it is not viable.
