ThinkPad X61s functions keys

Hi,

Running FreeBSD 7.0-RELEASE on a ThinkPad X61s.

Some keys do not work:

- volume adjustment
- screen brightness (FN HOME, FN END)

The keyboard light does work (FN-PgUp) as does
Numeric Lock (FN ScrLk).

What can I do to help diagnose the issue so we can get
these
functions working?

It seems that this script is never invoked.

Nothing hits /tmp/prova

I ran this loop while pressing keys:

while true; do clear; sysctl dev.acpi_ibm.0; date; sleep 1;
done

dev.acpi_ibm.0.%desc: IBM ThinkPad ACPI Extras
dev.acpi_ibm.0.%driver: acpi_ibm

I can get dev.acpi_ibm.0.thinklight to change when turning
off/on the think 
light.

I can get dev.acpi_ibm.0.hotkey to change between two
values: 2467 and 3491

That's it.  Nothing else.

With my T41, acpi_ibm was all I needed.

Dan,

FWIW, my T43p has never required any special treatment in
FreeBSD or Linux for
the volume adjustment, brightness adjustment or thinklight
keys to work.  Granted,
without acpi_ibm I cannot control those things via
software.

Elsewhere in this thread I had stated I'd solved the
problem.  I'm 
posting the details here.

I cannot get this set to 1 after boot:

$ grep ibm /etc/sysctl.conf
dev.acpi_ibm.0.events=1

$ sysctl dev.acpi_ibm.0.events
dev.acpi_ibm.0.events: 0

Under these circumstances, the keys will not work.  If I
manually set 
the events flag:

$ sudo sysctl dev.acpi_ibm.0.events=1
Password:
dev.acpi_ibm.0.events: 0 -> 1
$ sysctl dev.acpi_ibm.0.events
dev.acpi_ibm.0.events: 1


Then the brightness keys start working

This was the missing key.  The last line needs a trailing ;

Once I added that in, things started working.

Using the Fn key and pressing the F1-F12 keys, I get the
following log 
entrys in /tmp/prova:
Sun Apr 13 11:39:48 EDT 2008
0x01
Sun Apr 13 11:39:48 EDT 2008
0x02
Sun Apr 13 11:39:49 EDT 2008
0x03
Sun Apr 13 11:39:50 EDT 2008
0x05
Sun Apr 13 11:39:50 EDT 2008
0x06
Sun Apr 13 11:39:50 EDT 2008
0x07
Sun Apr 13 11:39:54 EDT 2008
0x08
Sun Apr 13 11:39:54 EDT 2008
0x09
Sun Apr 13 11:39:55 EDT 2008
0x0b
Sun Apr 13 11:39:55 EDT 2008
0x0c


Note the following exceptions which can be observed from the
above log 
entries:

Fn-F4 - sleep: does not give any log entry
Fn-F10 - unlabelled on the keyboard, gives no log entry

Other Fn key results:

SysReq - no log entry, no effect seen
NumLk - no log entry but system goes into NumLock mode
Pause - no log entry, no effect seen
ThinkLight - works, and creates a log entry 0x12
Spacebar - create log entry 0x14
