--------------
Kernel sources of the target kernel (some Linux distributions provide
  headers, makefiles and configuration data - it should suffice).
- Wireless Extensions support (14 or later, 17 preferred) - option
  CONFIG_NET_RADIO in kernel .config file.
- Sysctl support - option CONFIG_SYSCTL in kernel .config file.
- Crypto API support - option CONFIG_CRYPTO in kernel .config file (AES
  support is used if present, otherwise the AES-CCMP cipher module falls
  back to a private implementation).
- gcc of same version that was used to compile the kernel (ignoring this
  will cause "Invalid module format" errors during module load).
-------------------------------------------------
se hai installato il pacchetto dei moduli del kernel  dal cd   probabilmente vanno anche caricati 
per evitare  quella sfilza  di errori
