I guess what I *really* want to know is why you are messing with a
driver for hardware you don't have - for a computer which was
discontinued in 1998 - and translating a file that has not seen a
significant change in the entire Git era?  What benefit does this bring
to anybody?

You seem to be on a real mission to do these translations, but they are
not valuable for their own sake.  The kernel does not lack for churn as
it is.
