LibrePlanet says the PCI card is not supported by LinuxLibre
http://libreplanet.org/wiki/LinuxLibre:ATM_SOLOS
Two proprietary firmware blobs are involved. One of them is a FPGA
bitstream. According to the free hardware people they can only be synthesized
with proprietary software so the firmware could not be included in a GFSD
distro like Trisquel even if the source HDL was available under a free
license.
The first link after the Amazon ad on a search for 'solos pci adsl modem' on
DuckDuckGo is a vendor in Austria.
The ADSL modem chip in SoC of the ADSL2+ router on the DD-WRT homepage uses a
blob. I'll leave you to find out the status of that three year old beta
yourself. The DD-WRT forum Gurus are old school STFW & RTFM unless its a
smart question types. So the only way to get a definitive answer is to do
the reading.
