on disabling drivers that use non-Free firmware

[Richard M Stallman]

    Is it useless if the only thing it actually does is to inform the user
    that it won't work on a 100% Free system?

In general we want not to distribute programs that require non-free
software to work.

In general, when a device is not supported, do we want to give an error
report to say so?  That would be a nice feature, in some respects, but 
it would be a lot of work.
