Trisquel 6 Mini- Black border on AMD Raedon/Limited Resolution

I think that in Trisquel 6 by default radeon is blacklisted, which I find a surprising choice.

You can add a # in front of the blacklist line in /etc/modprobe.d/disable-radeon.conf and then update-initramfs -u. (Both these actions need to be done as root or using sudo.) Then reboot.

That alone could fix the resolution. That border could be there because of some theme used, not sure about this.

Just tried commenting out disable-radeon.conf, but no avail :(. Resolution is still limited. I figured out that the black border is due to overscan, but none of the solutions mentioned on google worked. I have tried other distros on the same card, and have gotten the following results:
Debian - Same issues.

Ubuntu / Lubuntu - Resolution is fine and the border is gone, but is getting a horrible score on the GPU benchmark.

gNewSense - Same issues.

The strangest part is that my UEFI splash screen even has the border now. Is the driver bare-metal or something? If only AMD and nVidia would be more open-source friendly...

I have a Radeon 9550 that worked fine with Trisquel 4.0 and Ubuntu 12.04 out of the box, but now its blacklisted in 6? Radeon is also deblobbled from the kernels as well.

I thought there were free drivers/firmware for these ATI cards. If there is, how can I restore them?

Well, the unfortunate fix is to install the FOSS driver (xserver-xorg-video-radeon) and the nonfree firmware. I got this information from the Debian IRC. They don't seem to be concerned that the firmware is not free.

For whatever reason, the AMD firmware is in the blobs section of the Linux Kernel:
http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/tree/firmware/WHENCE?id=HEAD

I'm surprised, as the license looks pretty free to me.
