Hi Steve,

That's a cool way to do it.  I wish I thought of it.
Here's yet another way by java:

public class lotsofhex55 {

        public static void main (String[] argv) {

                char myHex55;
                myHex55 = (char) 0x55;

                        // replace 256 with 262144 after testing
                for (int i = 0; i < 256; i++) {
                   System.out.print (myHex55);
        } // end main()
} // end class

Or, using standard *nix tools (Note: 0x55 = ascii U):
dd bs=1k count=256 if=/dev/zero | tr '\000' U  > full_of_0x55
