Current tpm_tis driver can not support new intel integrated TPM come with GM45 chipset.
In case of ThinkPad, R400/R500/T400/T500/W500/W700/X200/X301 models use this TPM. Actually most of laptop shipped from 2008 are using this TPM.
It seems iTPM has two problems
1) ACPI definition is not a EisaId style.
2) tpm_tis_status is wrong?
For the problem 1), we can use force=1 option to load...
