Mario, this mailing list really isn't for random programming-related 
questions. KDE-specific things, yes. "What is an RE", no.

That said, Jeroen's suggested RE has a beginning-of-line anchor (^) there, 
which you will want to remove, so the RE you want is

	#.*$

(An octothorpe, followed by whatever until the end of line). For completeness 
you probably want to chew up whitespace before the # as well, so that you 
leave your /boot/loader.conf in a minimal form.

You should be reading the file line-by-line, and dealing with possible 
backslash-continuations yourself (I'm unsure whether loader.conf allows it, 
though - it's parsed by a little forth program, nothing fancy).
