Seems like it would make a nice class:

class IPMI:
  def init(self,hwaddr,word = ""):
      self.__hwaddr = hwaddr
      self.__word = word

  def read(self):
     bytes = # do read from hardware
     word  = "".join([chr(byte) for byte in reversed(bytes)]
     return IPMI(self.__hwaddr,word)

  def __float__(self):
         return struct.unpack("f",self.__word))[0]

   def __int__(self):
         return struct.unpack("L",self.__word))[0]

   def __hex__(self):
         return long.__hex__(self,int(self))

   ... etc ..

Then you could just do:

ipmi1 = IPMI(foo_addr)
IConv = float(ipmi.read())

Or even make it iteratable...
