Well, does the OS or the fingerprint TPM handle the timeout? If the OS handles it (and potentially if the OS files themselves aren't completely and fully encrypted) then you can trick the OS into thinking it hasn't been 24-48 hours - all you need is for the fingerprint TPM to keep returning 'success'. If the TPM handles it then it is slightly harder to do.
