The Libre Tea Card is a little difficult though considering the fact that it
is a rolling release.
But yeah... you are right eoma68 isn't a product it is a standard which those
devices control.
LTCC as you call it is not for beginners though.
My best guess is persay The Practically Perfect or the Numero Uno... (but do
not enable the nonfree software repo and use linux libre!)
So really until trisquel supports arm I should just say, use libreboot!
The X200 is awesome for that purpose especially with 9 cell battery. :)
