jep sure this is nearly as I did it
function my_head() {
if( $_GET['page'] = 'mypage' {
// doit
}
}

but what I wanted to know is how to use the hooks which are especially
designed for not needing this:

admin_head-(page_hook) or admin_head-(plugin_page)
Runs in the HTML <head> section of the admin panel of a plugin-generated
page.

and

admin_print_scripts-(page_hook) or admin_print_scripts-(plugin_page)
Runs to print JavaScript scripts in the HTML head section of a specific
plugin-generated admin page.

(you will find them here:
http://codex.wordpress.org/Plugin_API/Action_Reference#Administrative_Actions)

This ones were my prefered way to do that - if I just could figure out, what
that stuff to add after the normal hookname is - everything I tried just
didn't do anything...
