So if this were to be implemented, syslinux needs to retain the memory, 
and there would be a new syslinux API call for going back to that state ?

Instead of HDT taking care of this, it would make more sense that memtest 
itself would perform the callback if it found syslinux hooks. And HDT 
could replace the syslinux state by its own ?
