Hi Ian,
I did try it using the real (bare-metal) grub 0.97 (in RHEL-5) to set 
the default out of range and it was set to the first entry so it matches 
the bare-metal grub behavior now. So the quiet mode was having it right 
all the time but interactive mode didn't so this is basically fix for 
interactive mode of pygrub.
