Put a FYI in the compatability shims so that people are aware that they

are using an old unconverted driver.  Most (if not all) of the drivers
for common hardware are newbus these days.  However, we don't want
to encourage people to take the easy way out and write new drivers
using the shims.  This is just passive "encouragement".
