Check /boot/config-XXXX file, which may have the following lines
CONFIG_PNPACPI=y CONFIG_PNP=y CONFIG_TCG_TPM=m CONFIG_TCG_TIS=m CONFIG_TCG_NSC=m CONFIG_TCG_ATMEL=m CONFIG_TCG_INFINEON=m
e.g. Thinkpad X60

Add following line to /etc/fstab
securityfs /sys/kernel/security securityfs rw 0 0
Install iasl. e.g. yum install iasl
cat /proc/acpi/dsdt > dsdt.dat iasl -d dsdt.dat
File, dsdt.dsl is generated.

This is new definiton. It seems current Linux PnP driver can't support this. use force=1 option with tpm_tis driver.
cat /proc/ioport
$ sudo apt-get install fakeroot build-essential makedumpfile $ sudo apt-get build-dep linux $ sudo apt-get build-dep linux-image-$(uname -r) $ apt-get source linux-image-$(uname -r)
Modify driver code, then just rebuild the tpm driver.
