Yes, I also searched a lot of hours for a solution. But there seems that
there is no solution. I think that the limitation is still in the BIOS,
no matter which tricks you try.

This would be cool from a technical point of view. But I see no real
world example where it would be helpful.
USB sticks are used because they are small and you can carry them in
your pocket. They are also useful for notebooks without CD-ROM. But when
you have to use the CD for booting USB sticks, all advantages are gone.
The only remaining advantage I see is that I can have my own customized
OS on the stick. Is that your purpose?
