[ltp] ACPI R40

hy, speaking of all this, i just switched to acpi on the R40 and
surprisingly i have a couple of question ... ;)
* swsusp (echo 4 >/proc/acpi/sleep) works fine except it doesnt shutdown
completely but i have to press the powerbutton for a few seconds (the
force method) to really power off.
* echo 3 doesnt, i.e. the laptop goes into the moon-mode (status light)
very quickly but i m not able to wake it up again, also i cant shut it
off with the power button but have to unplug ac, remove the battery.
* how do you map fn+F4 resp. fn+F12 keys to echo 3, 4?
i ve tried on 2.6.0-test9 and 2.6.0-test9-mm4, both show same behaviour.
as usual any hintz are appreciated.
