Compaq Evo N800v: I have a fixed DSDT table

[Daniele Boffi <boffi-piYtxHxN1XRAly3Pu9w1wA@public.gmane.org>]

Hi folks!

Stimulated by the recent discussions on the list, I made some important
progress on my (already satisfactory) fixed DSDT table for Evo N800v.

You can find it at

www-dimat.unipv.it/~boffi/compaq/custom-dsdt.hex

I'll send it to acpi.sf.net tonight.

IMPORTANT NOTICE: I am using Bios revision F.18A as of 2 Jan 03. Previous
release might not work.

What is working:

- batteries (BAT0  BAT1)
- ac_adapter (ACAD)
- button (lid  power  sleep)
- embedded_controller (C0D0)
- fan (I have 4 of them: C1D9  C1DA  C1DB  C1DC)
- power_resources (C0CF  C141  C155  C159  C15D  C166  C1D5  C1D6  C1D7  C1D8)
- processor (C000)
- thermal_zone (I have three of them, first one is CPU, TZ1  TZ2  TZ3)
- Fn F7/F8 work (panel brightness)
- pressing the lid button turns the screen off as expected

What can be improved

- sleep states: echo 5 works (shutdown), echo 4 works (it invokes swsusp)
                other states do nothing
- CPU: (*) I can change throttling state fine
       (*) performance always report P0, however I checked the following:
           turning AC/battery produced the desired effects (P1 when on battery)
           even if it is not reported in /proc/acpi
       (*) I can swicth to P1 when on AC with "echo 1:0 > limit" (always
           doesn't appear in proc/acpi), but "echo 0:0 > limit" does not switch
           back to P0. In order to switch back, I turn AC off for a second and
           then put it back, so that the BIOS does the job for me.
- volume control buttons: are they acpi-related?

I hope this will help somebody.

Daniele
