I don't think so.
T23 is not that old.
I also tried on my T41 before any success report, without any problems.

I think ACPI is the way to go. APM is OLD, and while there are some setups
where you cannot use ACPI and have to use APM, this is not your case. But
you need to upgrade to latest acpica patch for stability. Fn-F4 should
suspend your thinkpad if you have the right acpid scripts even without
ibm-acpi, but of course, with ibm-acpi you have more goodies.
