Hello. What an interesting thread :)
I just tried gNewSense 3 and it runs fine on my hardware, but there is one
catch not related to the hardware but still very painful and important - NO
recent web browser. The problem is that gns3 is not compatible with IceCat 17
which itself is fairy recent and usable (I still use year-old Firefox 17.0.x
ESR on Windows machines with no problems). I can browse FSF, GNU, Trisquel or
Gnewsense home pages using gns3 default browser (Mozilla 3.5 branch from
2009) but I would not dare to go somewhere else using that. I am well aware
that even 3.6 Mozilla branch is already too much outdated for doing anything
"mainstream" on the Internet.
I am an enthusiast of old things in computing. I am Amiga guy. I have
dedicated DOS gaming machine equipped with Soundblaster16 and S3 Virge cards.
And I am using XP where Windows is absolutely necessary.
But I also know that recent web browser is a must for a distro to be
practically usable.
On gns forum I just found an suggestion about backport of Iceweasel 17 for
Debian 6 being available but ... maybe just sticking to Trisquel 6 would be
just easier. So while I am a bit sentimental toward gNewSense and I am able
to install non-standard things into /opt directory, I must say now that I DO
NOT recommend to use gNewSense 3.
Sorry for having to say such a thing :(
