The T60 and T60p are supported by coreboot as well.

Some of the later Intel-based Thinkpad models (x200,x201,x230) have
coreboot support, but they have an auxiliary processor (called
Management Engine, ME) with remote management capability which can't be
disabled and that ME runs unknown closed-source code even if coreboot is

So if you're paranoid, the only Intel-based Thinkpad you can trust is a
T60/T60p/x60. AMD does not have a ME, but AFAIK no coreboot support for
an AMD-based Thinkpad exists.

The *61 series has a chipset not supported by coreboot, so although you
might be able to mod the hardware against some attacks, the firmware is
not trustable.

Yes. For now, at least.
