``Easily handle'' in what way? You can have a variable that holds 48
bits if the host supports more than 32 bits (usually, a long long).
But if you want to use it to poke around the address, using 48-bit far
pointer is going to be a system-dependent mess in many environments,
because of the different ways they implement memory protection (and
leave back doors for breaching it ;-).

Will $fiseg and $fioff be okay, then?
