 I'm not sure how delay works on amd64 at this early stage - the loop that
 fails does a KBD_DELAY, which is defined as 
 
 #define KBD_DELAY       DELAY(8)
 
 Can you try to increase this significantly (for testing only, of course),
 or change it to the lower case delay(...) variant?
 
 Maybe you could also try to compile this file (sys/dev/ic/pckbc.c) with -O0,
 to check for optimization problems.
