Mh, i just tried it and doesn't work for me :-(. Probably i am to tired and 
did a stupid mistake. But well i still can't load the it87 module. But my 
tree has the changes in superio.c. Hints are welcome :-). Probably im am 
missing a kernel driver or so?
Ward i have also the problem that i don't see any classic PCI cards on my 
machine (with linuxbios, works with stock bios), can you confirm this? I see 
all the nvidia stuff and the video card though.

I have written a small c program which reads out the values of the ec 
controller. It works for me under stock bios but gives "ff" on all reads 
under linuxbios :-(. Ward it would be nice if you could try it on your 
machine... and yes i was a little bit off with my statement can be take right 
of the datasheet. The program needs to be run as root or gives an access 
error.

Attached is also the output of the program on my machine under i386 and amd64. 
Keep in mind that some of the registers are fan and temperature input so they 
differ.

Concerning the question of Uwe, yes if you like i can maintain it on the wiki 
but i need an account?

Good night
ST
