I made an attempt with the new kp48 image.

These are the problems found:

• Power consumption problem is still present.
  Initially it seems that p. consumption is normal (discharge rate on idle = 1-3% / hour) but after 1-2 hours of continuos idle the situation changes and becomes "discharge rate on idle greater than 10% / hour"
• Lcd screen is always powered on.
  Maemo never turns off it, it only shows a black screen (with backlight on, this is evident on a dark room)
• There is problem with battery's charge measurement.
  I had 50% of reported battery's charge and I have rebooted the phone.
  After reboot reported battery's charge was only 7% and some mins after it was still 7%.
  I doubted that a boot process can really consume over 40% of battery's charge, so I have flashed, by multiboot, a PR1.3 kernel (with no u-boot).
  After reboot the reported battery's charge was 10% (greater than before) and some mins after it has raised to 39%
• It seems that bootmenu appears even with closed keyboard
