I'll update the wiki. Here are the detailed results:

T42-2378DXU linux 2.6.14.2 - tp_smapi 0.12

All

# cat /sys/devices/platform/smapi/BAT0/installed # cat 
# /sys/devices/platform/smapi/BAT0/state       # 
# idle/charging/discharging # cat 
# /sys/devices/platform/smapi/BAT0/cycle_count # cat 
# /sys/devices/platform/smapi/BAT0/current_now # instantaneous current 
# # cat /sys/devices/platform/smapi/BAT0/current_avg # last minute

# /sys/devices/platform/smapi/BAT0/barcoding # cat 
# /sys/devices/platform/smapi/BAT0/chemistry # cat 
# /sys/devices/platform/smapi/ac_connected

work fine

Both

atto:/# echo 1 > /sys/devices/platform/smapi/BAT0/force_discharge1
atto:/# echo 1 > /sys/devices/platform/smapi/BAT0/force_discharge2

work, but only

atto:/# cat /sys/devices/platform/smapi/BAT0/force_discharge1
1

responds.

atto:/# cat /sys/devices/platform/smapi/BAT0/force_discharge2
cat: /sys/devices/platform/smapi/BAT0/force_discharge2: Input/output 
error

fails

start_charge_thresh works:

# cat /sys/devices/platform/smapi/BAT0/start_charge_thresh 
10

but not 

cat: /sys/devices/platform/smapi/BAT0/stop_charge_thresh: Function not 
implemented

# cat /sys/devices/platform/smapi/BAT0/inhibit_charge_minutes
1
