[ltp] 2.6.23-rc3: brightness keys stopped working

[Marcus Better]

Hi,

I upgraded to kernel 2.6.23-rc3 and the brightness (and possibly other
function) keys stopped working. I'm not able to figure out reasonably
quickly whether I'm missing something obvious or if there's a problem with
the new thinkpad_acpi driver on my R60 laptop.

I have
  CONFIG_THINKPAD_ACPI=m
  CONFIG_THINKPAD_ACPI_DEBUG=y
  CONFIG_THINKPAD_ACPI_BAY=y
  CONFIG_THINKPAD_ACPI_INPUT_ENABLED=y

The input events seem to be generated:

~# input-events 6
/dev/input/event6
   bustype : BUS_HOST
   vendor  : 0x17aa
   product : 0x5054
   version : 16641
   name    : "ThinkPad Extra Buttons"
   phys    : "thinkpad_acpi/input0"
   bits ev : EV_SYN EV_KEY EV_MSC (null)

waiting for events
23:25:25.801797: EV_KEY KEY_BRIGHTNESSUP pressed
23:25:25.802111: EV_SYN code=0 value=0
23:25:25.802142: EV_KEY KEY_BRIGHTNESSUP released
23:25:25.802167: EV_SYN code=0 value=0

23:25:28.110018: EV_KEY KEY_BRIGHTNESSDOWN pressed
23:25:28.110285: EV_SYN code=0 value=0
23:25:28.110423: EV_KEY KEY_BRIGHTNESSDOWN released
23:25:28.110554: EV_SYN code=0 value=0


Also, the KDE on-screen display shows and adjusts a slider when I press the
keys, but there is no effect on the brightness except for an occasional
short blink of the screen.

I have Debian's hal 0.5.9.1-3.

Regards,

Marcus
