Comment(by frankprindle):

 I'd be glad to experiment, but my keyboard's refused to stick for over 2
 days, after getting worse and being nearly unusable for a day or two (no
 moisture issues here, just sitting on the counter powered up). I'm keeping
 a eye on it, as I don't trust spontaneous "cures".

 Joemck, I'd be cautious about drawing conclusions based on what you see in
 the keyboard diagnostic; I'm not sure it reflects the same reality as when
 running with the linux driver. A more telling test, which I'll run if mine
 ever starts sticking again, is to start the terminal activity, use "xset r
 ..." in a shell script to set every key to be repeating, and then just
 keep tapping keys to see if any normal keys stick (which will be obvious
 by the repeat), or only the "modifiers" (cntl, shift, fn, alt). Another
 way to check for sticking normal keys would be to run the Mini TamTam
 activity and listen for notes that stay on after they're released.

 The keyboard certainly has other quirks that are not intermittent. For
 example, in Mini TamTam, pressing the keys q-e-t-i, keeping each key down
 and pressing the next one in sequence produces a C-Major chord. But
 pressing i-t-e-q in the same way does not (though it seems as if it
 should). Pressing r-t-y in any sequence cannot make the full chord sound,
 only one or two notes at best. Curious children around the world will soon
 be asking their teachers why.
