Could they try to go with the truecrypt method? Instead of removing the password data off the device, replace it with "junk" data. "Low security" accounts that you wouldn't mind the "adversaries" having, sacrificial accounts, or even just a randomly generated selection of fake passwords for a selection of accounts, etc... It still won't fully protect you (obviously a "targeted" adversary would know that you have an account at "X" with "Y" username and the password in your vault doesn't work for that so tie him up!), but being able to hand over something when being questioned might be better than nothing for some.
