I too have this problem, with both NetBSD 0.9 and NetBSD-current and
solved it by never updating the LEDs on the console keyboard. At the
same time, I hard-coded my CapsLock key to be a Control key. The
diffs are as follows (BTW, pumpy is the name of the box that has this
problem, thus "ident PUMPY" in the kernel config file defines the CPP
symbol "PUMPY") :

Check out pcvt. To quote from the announcement:
