I put that line into /boot/device.hints which seems to work for getting the 
tweak to take.  When I attempt to suspend I get the following...

acpi0: AcpiGetSleepTypeData failed - AE_NOT_FOUND

That AE error is all over the place on boot up as well.  It never does go to 
suspend, just errors out.

Rebooting again with ACPI off and I can suspend without incident.  Must be 
some BIOS change between our Thinkpads here.

Later on,
