Okidoki. FWIW, the reason I never got any further was that my
experiments with other approaches proved somewhat inconclusive. Partly
because a reorganisation of my testbed has caused the physical
conditions to change which has caused the original problem to be less
severe.

So yeah, some wider testing would be good, and I agree that it is low
risk. I'll revisit this myself at some point after I get my testbed
rebased on a new kernel and figure out why the physical conditions
changed... :)
