Yeah, I hate that too, I'm in PAL land, but I have these PAL games that are converted from NTSC, so they have around 56 lines missing from the bottom. I like the games that allow you to choose NTSC or PAL (my TV supports both fortunately).
I read somewhere that you can change it in the boot options, much like an A1200, by holding the mouse buttons down, but I haven't done this yet.
