A good way to get everyone's attention would be to collect as many
drivers as possible that are almost certainly unused and move them to
drivers/staging/ with a warning like the above, as I just did for
drivers/wimax. That would make it to the usual news outlets
and lead to the remaining users (if any) noticing it so they can then
ask for the drivers to be moved back -- or decide it's time to let go
if the hardware can easily be replaced.
