Re: [ACPI-sppt] ASUS M2400N update > ASUS Centrino update

Hello, I think Robert's patch solved the problem for all Centrino, at
least on mine (M3N). This evening I'm going to add the original DSDT and 
this new one to the ACPI DSDT database. After the quotation, the results 
w/ the 'thermal' module on Linux kernel 2.4.21 and DSDT loaded from initrd.

=====

I think this is a forward step to permanently solve the ASUS's DSDT 
problem. I didn't need to rename the definition of '_LOO' as 'keventd' 
didn't take my CPU power.

It will be very useful if some other ASUS Centrino user could try this 
new hack, just to know if it works for them, too. More, if anyone knows 
a program to check the same temperature on Windows, please tell me, so 
we can compare the 2 different temperatures.

Thx, bye,
Gismo / Luca
