-.B load i2c/spi
-This loads the i2c or the spi drivers into the system and changes the permissions on
-the associated /dev/ entries so that the current user has access to them.
+.B load i2c [baudrate]
+This loads the i2c or drivers into the kernel and changes the permissions
+on the associated /dev/ entries so that the current user has access to
+them. Optionally it will set the I2C baudrate to that supplied (or as
+close as the Pi can manage) The default speed is 100Kb/sec.

+.B load spi [buffer size in KB]
+This loads the the spi drivers into the kernel and changes the permissions
