Yes, which is why you're only supposed to compile this on an i386  
machine and the resulting binary should be pushed to pc-bios by  
whoever commits this.

Isn't that the same as all the rest in pc-bios? Well - with the  
exception that this time we have the source and not only some  
patches ;-).

The relocations are always an issue. If you know about a magic  
compiler option that tells the compiler "scream of you find  
relocations", please tell me.
