I just use the following diretives: http://www.kriptopolis.org/node/673
(sorry is in spanish)
And everything was OK except that the wireless card didnt apear, probably I use a more updated version of the firmware.
But, I have a question for you guys: May I build a kernel lighter for my Dell i600m?
The thing is with this new kernel the Power Mgmt works fine, but I think I could profite more resources with a kernel that have only what I need. any suggestion or site for a laptop user?
