3232dK = 323.2K = 50C, and the small variation is presumably rounded.
So the DSDT appears to be reporting the wrong temperature. The DSDT
does look ok -- perhaps there's some problem with the SMIs? As a very
wild guess, try disabling 'Local APIC' in the kernel. That caused
hangs for me in conjunction with SMIs. And try the latest ACPI patch.

The Method that code is in doesn't get an argument, so Arg0 isn't
defined. Try replacing it by Local0. That shouldn't affect the
temperature, though, as it seems to handle the sleep button. Except if
the error confuses the ACPI implementation.
