Resources on fixing DSDT?

Resources on fixing DSDT?

[Thomas Tuttle]

I have an Asus M2400Ne with a screwed-up DSDT (some of the methods are renamed 
to proprietary names--A*** instead of _***--for Asus' proprietary power 
management stuff) and I have had no luck getting SpeedStep to work on it.  
(Everything else works!)  What I need to do is find the methods in the DSDT 
that are mis-named, re-name them, and patch my kernel to use the custom DSDT.

Can anyone either help me with this or point me to a good resource on how to do 
this?  I've looked at some tutorials on how to fix the DSDT but I have more 
problems than just syntax errors--I don't know which methods to rename, beyond 
just searching and replacing all A's with _'s... ;-)

Thanks in advance,

Thomas Tuttle

Isn't the M24N Centrino based? So i think you don't need bios support to 
get your throttling working... intel enhanced speedstep should be enough...

Yes...

Exactly--well it *should*!  The kernel module speedstep-centrino implements 
Enhanced SpeedStep, and neither it nor the ACPI Processor P[ower]-States module 
(stupidly named simply "acpi") will work--I get a "No such device" error when 
modprobing them with BIOS version 0200 and an oops when modprobing them with 
BIOS versions 0202 or 0203.

Any other suggestions?  Does anyone have a really good grasp of either ACPI P-
states or Enhanced SpeedStep who could help me decipher how to match up Asus' 
renamed functions with the real ones?

Please?  I'll throw in a Gmail invite... ;-)
