notebook buttons trouble, acpi related

[Hetfield]

hi,

i have a problem with my Asus a1000 notebook.

some buttons, like video switch, mute on/off, brightness up/down
are not detected by acpi nor keyboard driver.

the strange thing is that brightness works and video switch turn on/off
my tft (can't enable other video mode, but this is not a trouble).

if it turns off tft and change brightness i guess kernel should receive
some events but
/proc/acpi/event doesn't get them.

how can i see what happens when i press those keys?

acpi4asus doesn't support my notebook.

Thanks so much.

ps. of course, as usual, i'm ready to test every suggestions/ patches

In general, these keys generate events that are handled by the hardware.
The kernel never gets told about them. If you disassemble your DSDT, you
may be able to find methods that correspond to the hotkeys - then you
can use the ACPI generic hotkey driver to bind them to events. However,
this isn't always true and is very hardware dependent.

you could try the acerhk driver:

it doesn't seem to claim support for the a1000, but you may still have 
some luck...

sorry for the noise, asus != acer, no matter how many times you read it...
