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.
