Well... the idea was to release updates to the 12.04 image. I'd argue
definitely to add the xserver component (given Canonical did all the work for
it) and the kernel.
Ruben did half the work. There is a 3.5 kernel in the official repository and
there is an updated ISO with ar9271 firmware and kernel that was patched such
that the firmware would load (originally the 6.0 release's kernel was patched
such the firmware would not load even if it was free).
The 6.01 has not been publicized from what I can tell although does exist and
works great, but it is missing the 3.5 kernel, or anything newer:
http://devel.trisquel.info/makeiso/iso/trisquel_6.0.1_amd64.iso
After install you have to update to get the newer kernel:
1. Use the update manager to apply all updates
2. Search for linux-generic-lts-belenos in Synaptic Package Manager (System
Settings > Synaptic) and install the package
Or in a terminal run:
sudo apt-get update
sudo apt-get install linux-generic-lts-belenos
To install a more recent linux-libre kernel I'd follow the directions here:
