asus m5n, i2c-i805 missing temp1_auto_temp_min

[andy]

Hi list,

I have an asus m5n laptop, with kernel 2.6.16.9, and this works:

if cd '/sys/devices/pci0000:00/0000:00:1f.3/i2c-0/0-002e'; then
     echo 55000 > temp1_auto_temp_min
     echo 50000 > temp1_auto_temp_off
fi

However in kernel 2.6.16.27, and 2.6.17.7 it does not.  It reports that 
directory is not found (I can get to '/sys/devices/pci0000:00/' and 
thats it).  Its only for setting the fan on/off temp's, so its not a big 
deal, but it makes my laptop quieter when its not doing anything, so I 
kinda like it.

Is there a new way of doing this?  Or was it moved to another module? 
Or broken?

I am not subscribed to the lkml so if you need info from me please cc me 
directly.

Ahh yes, thank you very much.  I'm now the proud owner of a 2.6.17.7 kernel.
