I can't reproduce this currently, but it would be good to debug this further.  
My suggestions on how to do this would be to create an array of uint64_t and 
save TSC values (rdtsc()) into it at specific points in the atkbd/syscons 
console init.  You can then print out the deltas between array entries once 
the console is fully initialized.  Moving the rdtsc() calls around should 
allow one to determine where in the atkbd/syscons init the long pause is 
happening.
