Vi ricordate l'errore che ho avuto tentando di compilare i driver? 
Facendo una ricerca ho trovato questo, purtroppo non l'ho capito lo 
stesso. Cosa intende per "build for more than CONFIG_M386=y. "?
Ciao

Sure, build for more than CONFIG_M386=y.
I.e., build for a Pentium III etc. and it should work.
