Would you please elaborate? If I understand what you're saying, you
can't rely on the "pointer" returned by ioremap() because the OS
might reprogram the relevant BAR out from under you. So one would
need to know: when does a driver have to re-ioremap() due to the BAR
having been (potentially) changed? I'd expect the answer to be: for
all practical purposes never.
