The kernel is compiling fine now. I have been using it for a few hours.

I don't understand why some stuff are not included in
for example the sound chip or the v4l stuff for the webcam.

I also had to :
- add INPUT_EDEV to get the mouse and the keyboard under X (
- compile external wifi modules from

  to get proper Wifi performances (or I had to sit on the access point)
- get and compile the ec_module stuff from git
- had the PPP and bluetooth support for my 3G connection that's works
now with wvdial (thanks robert :))

The box is also complaining when it boots and try to set time :

xiwen ~ (n32) # hwclock  --debug
hwclock from util-linux-ng 2.14.2
hwclock: Open of /dev/rtc failed, errno=2: No such file or directory.
No usable clock interface found.
Cannot access the Hardware Clock via any known method.

I have seen some patches related to system clock in the git tree but i
don't understand.

What has to be included in the config tree to get suspend/hibernate and 
cpu_freq working  ? 
It seems to be linked to the clocking nope ?
