to do this automatically, change your /etc/rc.suspend and /etc/rc.resume
like this:

/etc.rc.suspend: insert this line just before the 'logger' line:

vidcontrol -s 2 < /dev/ttyv0


/etc/rc.resume: insert this line just before the 'logger' line:

vidcontrol -s 1 < /dev/ttyv0


Of course change the numbers if your X is running on a different tty.
That's a good enough fix for me.
