first of all nice work, you rock. My status report on X40 for the new
functions:

yes it is, according to windows

no idea, but current1 looks like present rate to me, and current2 like
some average over last minute?

yes, design_capacity is last_full_capacity and vice versa

hmm, i only noticed yet discharging is 40 d0 in first lines of
dump, c0 c0 is "charged". 

One thing i noticed, stop threshold isnt supported on x40 as i already
supported, but trying to set it, results in:

echo 90 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh

tp_smapi: battery 0: changed start threshold to 88
tp_smapi: SMAPI error: Function is not supported by SMAPI BIOS (func=211a)
tp_smapi: cannot get stop thresh of battery 0: Function is not supported by SMAPI BIOS

So even when stop failes, the values minus 2 will be set as start
threshold.
