Bug#404143: Fans unreliable under load, permanent memory leak

Matthew Garrett
A couple of observations:

* This bug will not cause hardware damage. The hard thermal cutoff
temperature is well below the temperature at which actual damage will
occur.

* It's not clear that the vendor DSDT is broken. It's an unusual
interpretation of the spec, but not necessarily an invalid one - sadly,
the ACPI specification is not entirely clear on every point.

The patch is /probably/ safe, and we've been shipping it in Ubuntu. On
the other hand, previous versions did cause problems on certain other
items of hardware. It's not clear what the best option is, but it's
certainly not a regression over Sarge.
