[ltp] Enabling special buttons in R61 and T510

[Janek S.]

I have two Thinkpads: R61 (openSUSE 11.3) and T510 (openSUSE 11.4) and I'm struggling to get the 
special keys (Fn+F[1-9] etc.) working. thinkpad_acpi (version 0.24) loads with no problems with 
0xFFFFFF hotkey mask and experimental=1 option. ACPI events seem to be generated properly. 
acpi_listen gives e.g.:
ibm/hotkey HKEY 00000080 00001002
ibm/hotkey HKEY 00000080 00001014

Brightness regulation works, ThinkLight and Fn+F5* also. Moreover, if I enable KMilo, then 
Fn+Space also works**. Nevertheless I do not know how to make use of other keys. I found that 
in /etc/acpi/events are configuration files responsible for handling ACPI events. By default 
there's a file called "thinkpad":

[root@GLaDOS : /etc/acpi/events] cat thinkpad
# forward acpi events to the thinkpad handler (bluetooth etc.)
event=ibm/.*
action=/etc/acpid/events/thinkpad_handler "%e"

thinkpad_handler contains:

[root@GLaDOS : /etc/acpi/events] cat ../actions/thinkpad_handler
#!/bin/bash

HOTKEY=$1
set $HOTKEY
EVENT=$1   # "ibm/hotkey"
ACPI=$2    # "HOTK"
WHAT=$3    # "00000080"
SERIAL=$4  # "0000100c" Fn+F12

# bluetooth
if [ "$WHAT" = "00000080" -a "$SERIAL" = "00001005" ]; then
        ACTION="disable"
        grep -q "disabled" "/proc/acpi/ibm/bluetooth" && ACTION="enable"
        echo $ACTION > "/proc/acpi/ibm/bluetooth"
fi

if [ "$WHAT" = "00000080" -a "$SERIAL" = "00001002" ]; then
        /opt/kde3/bin/kdesktop_lock -forcelock
fi

Bluetooth section is created by default, kdesktop_lock section was created by me and it doesn't 
seem to work. I followed these articles:

http://www.thinkwiki.org/wiki/How_to_get_special_keys_to_work
http://www.thinkwiki.org/wiki/How_to_configure_acpid
http://www.thinkwiki.org/wiki/Acpid

What am I doing wrong? The only sign that something may not be right is the statement from the 
last article: "[acpid] listens on a file (/proc/acpi/event)". When I try to display the contents 
of that file I get "resource busy" error.

*) On R61, Fn+F5 disables WiFi, but not Bluetooth. On T510 it seems to disable both WiFi and 
bluetooth. This is strange, since the thinkpad_acpi documentation states: "Enables/disables the 
internal Bluetooth hardware and W-WAN card if left in control of the firmware.  Does not affect 
the WLAN card.".

**) I disabled KMilo due to extremely anoying OSD. Is there a way to disable that OSD?
