if (sector == whatever the magic number is) {
   if (disk is larger than magic size
       && controller can handle LBA48)
       use LBA48;
   } else {
       use LBA32;

Or do the equivalent tests at device attach time, and just test a flag
or jump through a function pointer or whatever at disk access time.
