Hi,

from dmesg:

thinkpad_acpi: ThinkPad ACPI Extras v0.14
thinkpad_acpi: http://ibm-acpi.sf.net/
thinkpad_acpi: ThinkPad BIOS 7FETA0WW (2.18), EC 7FHT26WW-1.08
thinkpad_acpi: Lenovo ThinkPad Z61m
thinkpad_acpi: radio switch found; radios are enabled
input: ThinkPad Extra Buttons as /class/input/input11

brightness:
keys work. procfs and sysfs are updated correctly.
setting with procfs works.
sysfs accepts 30, 40, 50, 60, 70, 80, 90, 100 only. All other values do
not affect actual_brightness at all. I would expect that the next best
setting is used. (e.g. brightness=46 -> actual_brightness=50)

This is correct:
with ACPI video module:
- thinkpad_acpi hotkey events
- video acpi events
- brightness change

without ACPI video module:
- only thinkpad_acpi hotkey events


volume:
setting in procfs works and it is correctly updated when the keys are
used.

hotkey events:
I get events for:
<F1> - <F9>, <F11>, <F12>,
Begin/End (brightness up/down),
<space> (zoom)
ThinkVantage

No events for:
volume up/down/mute
<PgUp> (light)

thermal:
without experimental=1:
temperatures:   49 51 38 60 50 128 36 128
with experimental=1:
temperatures:   52 53 39 61 50 -128 36 -128 45 57 56 -128 -128 -128 -128
-128
Note that the unused elements are only -128 for experimental=1
as a result the corresponding files in sysfs return 128 instead of
"No such device or address" which is imho wrong.

Everything else seems to work as expected.
