No. HP is not just being obnoxious here.
This was implemented to prevent silent data corruption. 
In certain configurations (e.g B132L and a few other workstations),
Dino version 3.0 and older would silently corrupt data if the address
of the dino register passed over the bus as data.

A service note was published in ~1998-1999 time frame covering this.
Searching parisc-linux mailing list for "dino corruption" I didn't
find any direct references. I advise searching the HP website
directly. Or does some other HP person have a direct reference?

No. The only solution is to replace the machine with one
that is repaired. Sorry. :^(
