I use the following (tweak if you've patched your acpi to handle the
14-level brightness).

#!/bin/bash

if [ "`head -n1 /proc/acpi/ibm/brightness | cut -c 9-`" =3D "7" ]; then
        exit
fi

chvt 1
echo "level 7" > /proc/acpi/ibm/brightness
chvt 7

Suspend works on mine (barring USB bugs on resume regardless of
unloading modules) with nvidia.  I use S3 suspend to ram, the hibernate
scripts to automate unloading and restarting services, and sleep=3Ds3_bios
in the kernel cmdline.  The sleep cmdline option doesn't seem to be vital b=
ut
I've left it anyhow.

I haven't yet gotten TPM working with mine, however.
