 The macbook 2,1 is the same model as the X60. They are average computers and you will not be able to compile a kernel or a program from source as it would take far too long. Some fairly modern PCs can have the ME shrunk, they might be the better option after all.

The Libreboot project probably has more information on that. Feel free
to ask more information in their mailing list and add me in CC / TO if
you also want me to potentially reply.

Basically the more in depth information can be found in the hardware
documentation, more precisely the documentation of the chipset.

The documentation on the Intel I945 chipset explains that to have AMT on
such hardware you need to partition the BIOS flash chip, and it's
clearly not done with the stock BIOS on the Libreboot compatible
thinkpads with the Intel I945 chipset. There are probably additional
requirements but I didn't look into them. In laptops with an I945 that
are configured to run AMT, as I understand, the processor running it is
in the Ethernet controller. As I understand, with Libreboot the Ethernet
controller doesn't run any firmware.

For most GM45 Thinkpads compatible with Libreboot, with the stock BIOS,
the flash chip is already partitioned and the Management Engine is
enabled even if the laptop doesn't have AMT. Instead, with Libreboot,
the Management Engine is disabled by repartitioning the flash chip in a
way that tells the hardware that the Management Engine is disabled, and
by not adding the Management Engine firmware on the BIOS flash chip.
