You could try this: http://lists.debian.org/debian-bsd/2009/11/msg00006.html Download && compile the code (gcc -o chvt chvt.c). Add "$path/$to/chvt 1" to /etc/rc.suspend and "$path/$to/chvt 9" to /etc/rc.resume, so that your machine automatically changes to ttyv0 before going to sleep and changes back to X after waking up.
