OK Marc is right again. Marc, you have to stop this ;-)
So the operation is something like this:
disable_car copies stacks. The top of stack has a valid ROM address --
this code runs from ROM.
Disable_car returns to stage1. stage1 calls the next function. My only
worry is that happens to %ebp but ... this might be workable.
