The first thing I tried is "strings /dev/ram0" Which gave me quite a
long list, especially when Linux was bootet before ;)

I first thought this command might be useful for debugging, but probably
it isn't because usually one wants to pipe the result through grep to
limit the output. Also the next interesting thing to know is the
position of a string which this command does not tell us.

I won't apply it, but it's on the list for reference if someone wants to
use it. Maybe he/she can then tell us a good reason why this command should
be merged.
