If you're using -current, make sure that you have the following revision
of sys/dev/pckbc/pckbd.c:

/* $NetBSD: pckbd.c,v 1.29 2001/12/09 13:42:01 fvdl Exp $ */

It fixes a serious keyboard probing problem. If that doesn't help,
posting a log of the events sounds useful. If it's not 10,000 lines
long that is :)
