The attached diff attempts to eliminate as much of the difference between the i386 and the pc98 version of the file as possible. It should not make any semantic difference (it consists of whitespace changes, order changes, comment changes, changes of case for hex constants, and merging in a couple of constants that hadn't made it from the i386 version.)
