_TMP and _ACx (for TZ0):
Method (_AC0, 0, NotSerialized)
{
Return (C300 (C2F6, Zero))
}

Method (_AC1, 0, NotSerialized)
{
Return (C300 (C2F5, Zero))
}
Method (_AC2, 0, NotSerialized)
{
Return (C300 (C2F4, Zero))
}
Method (_AC3, 0, NotSerialized)
{
Return (C300 (C2F3, Zero))
}
Method (_CRT, 0, Serialized)
{
Return (C300 (0x04, Zero))
}
Method (_TMP, 0, Serialized)
{
Return (C305 (Zero))
}

1st trip point is at 50*C=0xC9E (not found).

Yes, I know this problem. Also is good idea compile i8042 as module [1]

Already I search solution for read-only trip points (control fans from
userspace)... [2]

[2] http://bugzilla.kernel.org/show_bug.cgi?id=8495 (rejected)

When I find any solution, then I think about test it. I don't risk using
latest kernel, when critical trip point is about 256*C...
