You can get the address of the real function that backs up any trap by
calling SysGetTrapAddress. But, keep in mind that the real address varies
with each OS release, and can vary dynamically as OS patches or hacks are
installed. (HackMaster and other hacks work by replacing the OS function
in the trap table with their own code.)
So, essentially you can build this list of addresses for OS functions any
time, just by calling SysGetTrapAddress is a loop. But, it will be
immediately out of date, so there's really no point!!
