I found really neat program called fbi.
fbi uses framebuffer console to view images. It's handy tool if you have a server and no X installed (or want to save resources by not running X).
Now my problem is when I try to view any pictire with it I get an error telling me that I have no permissions to open /dev/fb0.
I managed to bypass the problem by executing fbi with sudo.
cdmodding can't be done and I wouldn't like to do that anyways.

Do I need to add user dsl to some group(s) to make that work?

Any suggestions?

You might be able to fix it by changing permissions on /dev/fb0. For example, if you need write access to the device, you might chmod g+w and chown root.staff

I was trying to get fbi running in DSL as a uci a long while ago, had a problem relating to a font server, which I didn't understand, and so I gave up. Good luck.

Even if I was root I can't change permissions to /dev/fb0 or any other /dev/fb*.
It works just fine but that is the problem. As I said, it works just fine as running it as root.

What's the problem when you try to change the permission on /deb/fb0 ? What's the current permissions on them?

From google, it seems to be working for others... maybe just try and chmod 666 it.
