I solved this by changing it to a simple

               If(\_OSI ("Windows 2001")) 

as suggested by Martin earlier.

Anyway, I got the ACPI working fine for most functions, except:
- processor: no throttling (Pentium 4), but that may be out of the scope 
of ACPI(?)

processor id:            0
acpi id:                 0
bus mastering control:   no
power management:        yes
throttling control:      no
performance management:  no
limit interface:         no


- fan control/reporting
- thermal_zone and power_resource


The lid and power buttons are generating events after recompiling the DSDT table (they didn't before). Proper IRQ routing, battery and ac_adapter worked before.


As for the Fn-keys:

Fn-ESC (mute): doesn't work
Fn-F1 (screen lock): doesn't work
Fn-F2 (power toggle): doesn't work
Fn-F3 (suspend to RAM): doesn't work
Fn-F4 (hibernate): doesn't work
Fn-F5 (video switch): hangs the machine (read below)
Fn-F6/F7 (brightness): works
Fn-F8 (wireless toggle): works
Fn-F9 (touchpad toggle): works
Fn-F10/F11/F12: well, they should work anyway :)

I know some of these can be mapped to generate key events and call 
specific user programs. The one big problem I'm having now is with Fn-F5 
(video switch). With an older kernel version (2.4.20) it worked 
flawlessly, but with 2.4.22 (from Mandrake 9.2) it hangs the machine 
solid. I tried setting a serial console to check out any oops/kernel 
panic messages, even tried KDB, but alas, this machine doesn't have a 
serial port.

I searched around and found out that there's an USB serial console 
patch, but for kernel 2.5+.

I'm just beginning with ACPI, so if you have any suggestions on this, 
I'd be glad to hear. I'm still reading the 500+ page tome of the ACPI 
spec... :)
