"MEI device not found". I take it that's good news?

Hello there- I'm assuming this is the right way to ask a general question, but please let me know if it isn't.
I have an "X62" laptop, which is actually an old Thinkpad X61 with a custom motherboard in it. This board has an i7-5600u CPU on it, and I was wondering if it was possible to build a version of coreboot for this machine. I see an existing mailing list entry in the archive discussing a Chromebook Pixel with the same CPU, so I'm thinking it may be possible unless I'm missing something major. Since this is a custom motherboard, how would I find out about the Intel Boot Guard and related issues so that I can provide the details for the good folks here?
You can try https://review.coreboot.org/#/c/16328/, or modify some instructions in the firmware to see if it still boots.
If boot guard is not enabled, I think booting with coreboot is not so hard, but it may be hard to make the EC interface work fine.

I'm pretty comfortable around Linux but probably would have trouble
building this from scratch. Thanks in advance!

What appears in lspci has no bearing on what is actually DMA capable. You have the same effect by using the ME option ROM to set it to "disabled" but how do you know it is really disabled? you don't.
