You're not going to be able to do it in any way other than adaptively
since the order isn't in hardwired in the source code at all. It's
entirely dependent on the order in which the drivers are loaded, which
in turn is going to depend on a) which drivers are present on the
user's system, and b) which ones actually detected hardware and
installed a corresponding interrupt handler, which is, of course,
dependent on what hardware the user actually has.
