I suppose in the worst case where the perpetrator intended to hide the 
fact, one would have to use behaviour (intended an non-intended) to see 
the violation. For the ignorant aren't there various strings in unstripped 
code that be evidence? Also won't code compiled in the same way produce 
fairly similar results? There may be symbols exported or imported into the 
code giving some idea as to what it is about. An strace or ltrace could 
show a predictable sequence of calls.

In this case they are drivers so I'd expect them to be stripped, but have 
symbols and parameters, descriptions, etc.
