Looks like either the T61 firmware is specially broken, or something
broke thinkpad-acpi. Which kernel? Which firmware?
The driver resets the masks and everything else on resume, or at least
it is supposed to do that. Maybe hotkey_resume() is not being called on
your kernel for some reason. The relevant code is in:
