 I'm afraid that I already have version 1.75:
 
 tron@lyssa:~>grep NetBSD /usr/src/sys/arch/i386/include/param.h 
 /*      $NetBSD: param.h,v 1.75 2012/02/04 17:56:16 para Exp $  */
 
 I've also tried to reduce the amount of memory of the virtual machine
 to 2GB and it still locked up.
 
        Kind regards
