Thank you, and yes, it is a good idea to gray out the UUID and SN, we don't
need or want them.

Can you please send the output of recent acpidump to me by private email?
You are using the latest T21 BIOS, and a full ACPI dump can be quite
valuable for my work in thinkpad-acpi.

I think the best way to go about this, as long as we don't get reports from
many other boxes failing to resume or hitting ACPI EC problems, is to add a
"slow_thinkpad_ec" quirk, and use dmi matches to enable it on the T21 and
other thinkpads of that vintage (definately all of the T2x and A2x, maybe a
few others.  I have a candidate list here that I assembled for other
reasons.
