Comment (by jg):

 Replying to [comment:3 wmb at firmworks.com]:
 > The root cause is that the ALPS keyboard seems to send an extra ACK
 after the KBD_RESET command (ff) if you neglect to consume the data value
 (e0) returned after the 8042 "test lines" command.
 >
 > That extra ack caused kbd-reset to fail because, instead of receiving
 the expected "fa aa" response from the "ff" command, it instead received
 "fa fa aa", i.e. two acks.

 If this breaks the PS/2 spec, we should bother to tell alps before closing
 this bug.  Thankfully, Linux doesn't care.
