My system is an A2000 8/2 ram, 2091.  I'm using 1.0.  And I can confirm
this is not related to X at all.  This problem occurs during heavy disk
access, and most noticibly when the daily scripts run at night.  The
keyboard stream would only type capital letters, and if I press the caps
lock key, the light will come on, and the keyboard would type lower-case
letters.  But if I tap it a few more times, the caps come back to normal. 
Several times, the entire console would lock up, and quite a while later,
I'll get a login: and it'll print "repeating too fast" or some error like
