Run OFW heat spreader test

We are using a custom olpc.fth to present a boot menu so that users
can easily flash their XOs. As a precaution, we run a lid switches
test before the OS installation begins. Some of our XOs have older,
less effective heat spreaders, and we would like to catch these before
they get burnt-out by the flashing process.

The automatic lid switches test is confusing some teachers. Ideally we
only want to run the heat spreader test part of it, so that the test
is transparent and the user doesn't need to close the lid.

Is this possible?

Further to this, is it possible to reliably parse the result and halt
the OS flashing if the test fails?
