Well, you're saying somebody has to do it, right? Is it easier
to fob this off to upper layers that (frankly) don't care what
hardware they're talking to!? This means we have N copies
of this, and N ways to do it. Talk about cacheline pingpong.

Sorry but it suddenly sounds like we're all writing device
drivers, not developing upper layers. This is a mistake.
