I've got me a macbook and I'm figuring out how to install OpenBSD on

it (I'm going to see if I can do it without BootCamp, appearently it's

possible: http://refit.sourceforge.net/myths/). One of my friends

mentioned "too bad about the evil" to me and so I started digging into

one of the evils: Trusted Computing. How do I find out if this mac has

a TPM chip? Apple is never open about this fact.
This page

reports that some macs have them and some don't. It also says that in

linux you can check `ioreg` for mentions of TPM.
What would the equivalent method in OpenBSD? Would the chip show up in

dmesg? Here's one dmesg

http://erdelynet.com/tech/openbsd/openbsd-on-intel-mac-mini/ and I

don't see anything that looks like a TPM chip but I'm not sure what

all the devices are.
If I can't know for sure from software I plan on cracking the case and

searching for one physically anyway.
