Comment(by greenfeld):
Replying to [comment:5 martin.langhoff]:
> More worrying is that even using the power btn to wake it up, we lose
keyb and tp input completely, perhaps 20% of the time. The machine in this
state does work with a USB keyboard. So the machine quicky becomes
unusable with aggressive S/R.

I'm not 100% certain this is the case; we need to full separate "the
failure to wake up from PS/2 input but it gets queued" action from the
"PS/2 input failing when power/game button is used to wake up".
Data may be partially overflowing and overwriting the PS/2 buffer(s)
before we realize we need to use the power button to reset, which could
potentially give OFW gibberish to work with when it finally does wake up
the laptop.
