Hi, the best thing you could try is booting the machine from a live CD or DVD and then taking a snapshot of the output of the command:
It will be a long output but you should be able to cut/paste it to a text file and email it to yourself or drop it into the local file system on the machine if its possible to mount the hard drive (usually on the gnome desktop you can browse the machines hard drives using a file manager and that should auto-mount it for you). You should then be able to compare your live CD/DVD with your machine.
Interestingly enough Im running Ubuntu (10.04) and I know Mint is based on the same kernel, your /etc would be similar to mine I'd think. I have flash installed but I dont see any reference to it in /etc, heres my output
$ ls -la /etc/lib*
-rw-r--r-- 1 root root 20 2010-03-06 15:05 /etc/libao.conf
drwxr-xr-x 2 root root 4096 2010-03-06 20:22 .
drwxr-xr-x 174 root root 12288 2013-05-01 14:37 ..
