 * These are here the very lowlevel bankswitching routines.
 * The segment to switch to is passed via %eax. Only %eax and %edx my be used
 * without saving the original contents.
 *
 * WHY ASSEMBLY LANGUAGE ???
 *
 * These routines must be callable by other assembly routines. But I don't
 * want to have the overhead of pushing and poping the normal stack-frame.
