13	* bus_speed (unsigned int)
14	Allows changing of the bus speed.  Normally, the bus speed is set by the BIOS
15	and never needs to be changed.  However, some SMBus analyzers are too slow for
16	monitoring the bus during debug, thus the need for this module parameter.
17	Specify the bus speed in kHz.
18	Available bus frequency settings:
19	  0  no change
20	  80 kHz
21	  100 kHz
22	  400 kHz
23	  1000 kHz
