Hmm, do you think it is best to do this on a per-device level vs a per-driver
level (e.g. a 'hw.<driver>.msi' tunable ala mfi(4))? Also, I think it is
better to have a flag whose value more closely matches enable/disable (so 1
for enable, etc.) and default it to on, than to have a 'disable' tunable.
