Installing rt2570 module

[Xan <dxpublica@telefonica.net>]

Hi,

I just installed Debian as it described in  
http://www.cyrius.com/debian/nslu2/.

I have conceptronic usb wifi that are supported by the rt2570 driver.

So, I want to install this module in my original kernel. The problem is 
that I don't know how to do it. I'm a newbee.

I found 
http://rt2x00.serialmonkey.com/wiki/index.php?title=Debian_rt2500_Howto 
and http://www.nslu2-linux.org/wiki/DebianSlug/InstallRT2570 and these 
differ.

For the other hand, I don't want to download kernel headers as it 
described in http://www.nslu2-linux.org/wiki/DebianSlug/InstallRT2570. I 
want to build myself. But I don't know how.

In resume, what's the easy and standard way for inserting rt2570 module 
and that usb wiki key works?

Thanks a lot in advance,
Xan.
