 uwe mentions this:
 
                     0xe6, 0xe8, 0x00, 0xe8, 0x00,
                     0xe8, 0x00, 0xe8, 0x03, 0xf3,
                     0xc8,
 
 effectively hard-codes the 'psmouse sliced command' which multiple
 things use (and then some).
 
 In the words of otherOS:
 
  * psmouse_sliced_command() sends an extended PS/2 command to the mouse
  * using sliced syntax, understood by advanced devices, such as Logitech
  * or Synaptics touchpads. The command is encoded as:
  * 0xE6 0xE8 rr 0xE8 ss 0xE8 tt 0xE8 uu where (rr*64)+(ss*16)+(tt*4)+uu
 
 The documentation/other drivers use sliced commands.
