I have modified the rc.local file to get keyboard lights on get the internal swap working and to stop the wlan number incremental. See here.
Code:
#!/bin/sh -e
hwclock -u -s
loadkeys /lib/udev/keymaps/nokia-n900-keys.map
ifconfig wlan16 hw ether 00:1f:df:89:02:89
echo "120" > /sys/class/leds/lp5523:channel0/brightness
echo "120" > /sys/class/leds/lp5523:channel1/brightness
echo "120" > /sys/class/leds/lp5523:channel2/brightness
echo "120" > /sys/class/leds/lp5523:channel3/brightness
echo "120" > /sys/class/leds/lp5523:channel7/brightness
echo "120" > /sys/class/leds/lp5523:channel8/brightness

I've found a charging script which seems to be working: link (I am not responsible if something goes wrong. Do not use this unless you now what are you doing.)
I've installed i2c-tools, libi2c-dev and python-smbus.
Code:
i2cset -y -m 0x77 2 0x6b 0x04 0xc9;
status=$(i2cget -y 2 0x6b 0x00)
echo status=$status

# next register 0x03 is device ID, always 4b and r/o; so we skip to 0x04
i2cset -y -m 0xff 2 0x6b 0x02 0x8c;
# 0x8c = 3v5 + .640 + .040 + .020 = 4V200, BE CAREFUL and DON'T CHANGE
# unless you know what you're doing. 4V2 is ABS MAX!
i2cset -y -m 0xff 2 0x6b 0x01 0xc8;
i2cset -y -m 0xc0 2 0x6b 0x00 0x00;

# tickle watchdog, while status indicates 'charging from wallcharger'
#while [ $(i2cget -y 2 0x6b 0x00) = 0x90 ] ; do
while [ $(i2cget -y 2 0x6b 0x00) = 0x10 ] ; do
	echo charging...
	sleep 28;
	# reset watchdog timer:
	i2cset -y -m 0x80 2 0x6b 0x00 0x80
done
echo "charging finished, status(reg0)=$(i2cget -y 2 0x6b 0x00)"
Charging seems to be working as my script show the increase of the voltage and the percentage as well.
