Robert,

ACPI doesn't work at all with the T21. In fact, you'll want to add 
acpi=no to your bootloader.

I wrote an article about the T21 recently in:

http://www.linuxjournal.com/article/8462

While loading gentoo, I suggest you bring emerge configure-thinkpad. It
will give you the information you need regarding acpi and it's a great
tool for the thinkpad.

Good luck!
