If you look at the lisp code for find-grep-dired (in 
.../lisp/find-dired.el) you will see that it constructs the find command 
line as follows:

      (find-dired dir
               (concat "-type f -exec " grep-program " "
    find-grep-options " -e "
                   (shell-quote-argument regexp)
                   " "
                   (shell-quote-argument "{}")
                   " "
                   (shell-quote-argument ";"))))

find-grep-options is defined by default as "-q" on Linux, so you could 
just set it with:

   (setq find-grep-options "-q -i")

Put this in your .emacs file and all your find-grep and find-grep-dired 
commands will be case-insensitive.
