Can you recover from this situation? My laptop hangs *hard* when I try
to suspend from within X, so I wrote a small wrapper to switch to a
text console before running `apm -z` which I keep in /usr/local/bin.
You should also change /etc/apmd.conf to invoke this zzz rather than
the standard one.

Tony.
