I gave up on the "one size fits all" power management utilities for my T23 and went back to my scripts. I did learn enough that I retained the uswsusp package and use its s2disk utility. I also use powernowd and KDE's battery monitor.

My script is 100% reliable suspending to RAM while the various other utilities were not. I do think that the T23 is old enough that it doesn't support ACPI all that well even with BIOS updates. So my manual scripts work well with it.
