catalyst 9.4 and suspend/hibernate hints

i had some issues using suspend with the new catalyst drivers, xorg 1.6 and kernel 2.6.29.
i use the simple "echo disk > /sys/power/state" command and it worked great so far.
since the upgrades it ran quite unstable and unpredictable.
however, i found a workaround. that's what i did:

#!/bin/bash
# Switch to tty1 (dirty workaround)
chvt 1

# when not running this it hangs!
rm -f /etc/ati/amdpcsdb

# hibernate
echo "disk" > /sys/power/state

# ... and back to X
(sleep 2 && chvt 7) &

now it works reliable for me.
hope this helps someone.
