Yes, you are working below the OS.  These functions are not part of the API and can 
change from OS version to OS version.

No, the only application accessible interrupt service routine is in the Handspring 
extensions.  If you are this hard up for total
control I suggest you either wipe the Palm device clean of the OS all together to 
write your own or develop a Springboard device to
get the level of control that you apparently need.
