There are already a couple of syscall reservations in entry.S for kexec 
and vserver. What makes these so special?

Yes but its easier to simply replace the sys_ni_syscall with the function 
call when it finally hits mainline. If the number stays the same then the user
space source using this function calls do not have to be redone and work 
on library maintenance can proceed concurrently.
