(In reply to comment #86)

The new address is correct, but the script is not usable because I observe a
different behaviour now (I suppose it started with 1.3x series of BIOSes
introducing WMI1 Device in DSDT):

My Aspire 5715z has 32-bit and 64-bit Hardy Heron, and Vista Home Basic
installed. Regardless of cold boot or return from stanby of the said OSes
(including Vista w/Acer's ePower thing running), I suffer overcooling.
Also, the following message that appeared in kern.log everytime fan was turned
on/off has vanished (which, I suppose, is a Good Thing):
    APIC error on CPU0: 40(40)


The regular observation is fan starting @50C, and stopping @45C (TZ01/temp
reading). 
However, sometimes it starts around 40-45C, albeit quieter than that @50C.
TZ01/temp quickly drops to 40, then to 35. Coretemp readings go way lower.
At this point patching the value 2828 (or lower) no longer stops the fan, I
have to patch a 50C (3232) first. Because, I suppose, the firmware to turn it
off is not aware of an active fan triggered somewhere @40-45C, hence assumes
the fan is off at 45C or lower.

I wonder why noone else complains about overcooling. Maybe it occurs with T2330
processor only. 
Note: setting polling_frequency had no effect so far.
