  I'm in confusion now as well.

  My 5000/260 just started doing this.  I had just built a 1.4 install
kernel and was going to test installing 1.4 on another disk.  I hooked up
another expansion cabinet to the SCSI bus.  I then started seeing extra
"keystrokes" - even while in the PROM.

  What appears to be happening in my case is that I seem to be getting a
keyboard character when releasing a key.  I.e. if I press and hold a,
press b, then release a and then b, I will see "aba".  It looks very
simliar to what Simon shows above.  Simon - what kind of keyboard are you
using?  I think mine is currently an LK401.  When I get done playing with
the install, I'm going to hook up an LK201 and see if that makes any
difference.
