Well, I have purchased my laptop from Zareason: https://zareason.com
They do not offer Trisquel explicitly, but can install it (as well as any other Linux distribution of the customer's choice) upon request.
I've got a fully functional laptop with a minor issue regarding the CPU temperature. That has been easily fixed by installing lm-sensors.
Trisquel works out of the box, and maybe if they get enough requests they will list it among the the available distros.
