I've seen this on two FreeBSD 4.7 systems connected via a KVM (sharing 
with two Windows 2003 servers)... typing at the console of them was 
almost like typing via ssh on a satellite connection. Connecting via ssh 
was fine, it was only locally that it was a problem. Resetting the 
keyboard repeat rate on BSD had no discernible impact.

I put it down to some sort of interaction between the KVM, the Windows 
servers and FreeBSD and put up with it...
