Whoever wrote that BIOS needs to figure out that specification calls for
_TMP, _CRT, _PSV and _ACx methods to return value, measured in 0.1K.
Hence, -270.9 is, likely, 24C. If you feel adventurous, you might want
to change your _TMP method by adding 
                            Multiply (0x0A, Local0, Local0)
                            Add (Local0, 0x0AAC, Local0)
before 
	Return (Local0)

_CRT, _PSV and _AC0 could use the same treatment.

HTH,
